Some grammar mistake With the consumption of fossil fuels and the emission of greenhouse gases, the development of new sustainable energy production technologies has been regarded as one of the first tasks of mankind. The monoclinic BiVO4(m-BiVO4) has the advantage of a narrow band, non-toxic, low price, stable chemical and light properties. In this work, we have improved the photocatalytic performance of m-BiVO4 by synthesized homojuctional semiconductors, metal doping and tuning exposed facets. The samples were chareacterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM), ultraviolet-visible diffuse reflectance (UV-vis), X-ray photoelectron spectroscopy (XPS), Energy Dispersive X-Ray Spectroscopy(EDX) and Photoluminescence Spectroscopy(PL). Explore the growth mechanism of the photocatalyst and study the relationship between its structure and photocatalytic performance. Under the hydrothermal condition of pH = 2, 180 °C and 24 h, BiVO4 was synthesized by hydrothermal method using Bi(NO3)3·5H2O and NH4VO3 as raw materials, Na2WO4 solutions were added as a crystal phase transfer inhibitor enables the BiVO4 photocatalyst to form a monoclinic phase while a disordered amorphous layer appears on the surface. The XRD, EDX and XPS analysis showed that the addition of a small amount of Na2WO4 solution during the synthesis process did not change the crystal phase of the m-BiVO4 photocatalyst and no impurity ions were introduced into the lattice. The photocatalytic O2-evolution activities of as-prepared m-BiVO4 samples have been investigated in 200 mL of aqueous AgNO3 solution (0.05 M) under visible light irradiation (λ ≥ 420 nm). The average rates of the m-BiVO4-500 is 722.8 mmol h-1 g-1 and the average rate is 21.2 times that of m-BiVO4-0 sample. The electrochemical water-oxidation performance of as-prepared m-BiVO4 samples showed that the m-BiVO4-500 sample behaves with the current density of 12.8 µA cm-2, which is 8.8 times as high as that of m-BiVO4-0 sample.This is attributed to a synergetic effect of homojuctions between the disordered amorphous layers on the surface and the coated monoclinic crystal particles as well as oxygen vacancies. The amorphous layers are generated from the formation of oxygen vacancies on the surface of m-BiVO4. The homostructural junction enhances the hole-electron separation and the oxygen vacancies provide the active sites for water oxidation. Since addition of excessive Na2WO4 solution w

which one is right 1.the furgrine is exactly what I want that u presented to me as the NEW YEAR GIFT 2.the furgrine that u presented to me as the NEW YEAR GIFT is what i want . which one is correct？ please tell me why .much obliged for u ！

a small paragraph there's must something infrequent in living memories：friendship.family love or tendresse…and So on .everything about love called“happiness for us”.So do i. neither i can avoid this normality.cause i have the dearest families that loves me.andbest the best friends who are always uphold my all .everything i have is enough to me. what human have is a great love. i will do my best for my possesions and a better tomorrow than today forever

what i have is love what i have is love there's must something infrequent in living memories：friendship.family love or tendresse…and So on .everything about love called“happiness for us”.So do i. neither i can avoid this normality.cause i have the dearest families that loves me.andbest the best friends who are always uphold my all .everything i have is enough to me. what human have is a great love. i will do my best for my possesions and a better tomorrow than today forever

a few questions who can tell me the difference between these words…？I'll be obliged with your corrects：） 1.like to be & tend to？ ①the advantages like to be women ②healthy spending tends to rise disproportionately in this country. 2.in order to & towards for example ①i meditate in order to relax. ②i saves half of my salary towards buying a house in a few years 3.abrupt &spring up come to an abrupt end doubt to spring up in my mind

make some sentence i wish someone could correct me thank u make some sentence 1.Who says fairness is everywhere?no i find it difficult to remain objective where ownself are concerned：）maybe i need more distressing experience for my heart maintenance.yeah I admit that I am not a saint.who is？ 2.TianKeLong——The once great n giggest industry in our town is now in terminal decline. NO more traces of it but FULL of warm memories of my childhood 3.Reciting Engwords is So freakinng the most disgusting thing, always forget just recited 4.No matter when i think i can't try to magnify the part i played in everything What if something happens？？？……What therapy？Electroshock therapy like professor Yang? 5.When I meet my lover someday in the future.i must knit him a sweater！i also want to cook for him in perso…emmmm or who can give me some lateral idea？whatever I'll give you everything for my best. at this very moment i look forward to u don't lag far behind me 6.u know I hate noisy children. I only like good ones.So i don' want to sit for ur child 7.there's a tenderness that radiated from u.if u say“not at all”then our IDEOLOGY are different.

notitled hope someone could correct my note below： for this moment at least. I physically cannot sleep in .something what stucking with me all day.I'm tossing and turning now.i once thought i can stand beside someone in eternity. but it's just a huge ridiculous joke so far as today.i don't know why god likes kiding me. i think it's only a monologue by myself. why do this all？i don't know and don't want to thinking it again.it's rather cold this afternoon that maybe lead me to catch a cold.i feel really not well now.bacause i have a little headache .i don't go to work tomorrow.even So i think i must go sleel now instead considering those comial n meaningless things.I gotta work on that.i trust that everything will be going well.everyonelf.to the love ya'll.say bye for myself.

a few sentences Hope someone could correct me.thanks：） 1.how old do the most people usually get married in your country？ 2.you looks like very love the cat.aren't you？ 3.there's a fairly magical story happened at me 4.i can't sleep until now.my dad n my mon eithernow.cause my dog is always barking 5.i don't know what can i do now.i just know that i must go sleep now.and the day after day still nice.everyone are fine.include me. 6.So did u go china study to see beautiful women？（a man who go to the china to study .because he can look many beautiful girls） 7.the book on the tale are what u want.isn't it？ 8.dear me . why don't your school haven't Chinese course
