Sezvo mhoteredzo inoshata, vanhu vanoramba vachiwedzera kucherechedza kuchengetedzwa kwezvakatipoteredza.Dzimwe nzira dzechinyakare dzekuchenesa mvura yetsvina dzakaoma kuzadzisa zvinodiwa zvebudiriro nekuda kwezvizhinji zvezvigadzirwa, yakaoma post-kurapwa, kusvibiswa kwechipiri uye zvimwe zvinogumira.Photocatalytic oxidation tekinoroji yakagamuchira tarisiro yakawedzera kune yayo yakanakisa mabhenefiti senge yakaderera simba rekushandisa, zvinyoro maitiro mamiriro, nyore kushanda, uye hapana kusvibiswa kwechipiri.
Semiconductor photocatalysis zvinoreva kuti semiconductor catalyst inogadzira electron-hole pairs pasi pechiito chechiedza chinooneka kana ultraviolet chiedza.Iye O2, H2O uye mamorekuru anosvibisa adsorbed pamusoro pe semiconductor pamusoro anogamuchira maerekitironi anogadzirwa nemifananidzo kana maburi, uye nhevedzano yezvekuita redox inoitika.Ndiyo nzira yakadai yephotochemical yekudzikisa zvinosvibisa zvine chepfu kuita zvisiri-chepfu kana zvishoma zvine chepfu.Iyi nzira inogona kuitwa pakamuri tembiricha, inogona kushandisa chiedza chezuva, ine huwandu hwakawanda hwezvinokonzeresa masosi, isingadhure, isiri-chepfu, yakagadzikana, uye inoshandiswazve kushandiswa, hapana kusvibiswa kwechipiri uye zvimwe zvakanakira.Parizvino, akawanda mafotocatalyst anoshatisa organic zvinosvibisa N-mhando semiconductor zvinhu, seTiO.2, ZnO, CdS, WO, SnO2, Fe2O3, nezvimwewo.
Mumakore achangopfuura, senzira inoshanda, photocatalytic tekinoroji ine yakanaka yekurapa maitiro pane zvinosvibisa zvakatipoteredza.Pakati pavo, semiconductor heterogeneous photocatalysis yave yakanyanya kutarisisa ziso tekinoroji nekuti inogona kukonzeresa uye kushatisa zvakasiyana-siyana organic uye inorganic zvinhu mumhepo yakasviba uye tsvina.Iyi tekinoroji inogona kukanganisa zvachose akawanda organic zvinosvibisa muCO2, H2O, C1-, P043- uye zvimwe inorganic zvinhu, kuderedza zvakanyanya iyo yakazara organic yemukati (TOC) yehurongwa;zvakawanda inorganic zvinosvibisa seCN-, NOx, NH3, H2S, nezvimwe zvinogona zvakare kuderedzwa kuburikidza nephotocatalytic reactions.
Pakati peakawanda semiconductor photocatalysts, titanium dioxide uye nano cuprous oxide zvagara zviri musimboti wephotocatalysis tsvakiridzo nekuda kwekusimba kwavo oxidizing kugona, yakakwirira catalytic chiitiko, uye kugadzikana kwakanaka.Nyanzvi dzakawanda dzinotenda kuti Cu2O ine tarisiro yakanaka yekushandisa mu photocatalytic degradation ye organic pollutants, uye inotarisirwa kuve chizvarwa chitsva che semiconductor photocatalysts mushure metitanium dioxide.Cu2O nano ine yakagadzikana makemikari zvimiro uye yakasimba oxidizing kugona pasi pekuita kwechiedza chezuva, icho chinogona kupedzisira chakazara oxidize organic zvinosvibisa mumvura kugadzira CO.2uye H2O. Naizvozvo, nano Cu2O inonyanya kukodzera kurapwa kwepamusoro kwemvura yakasvibiswa yedhayi.Vatsvakurudzi vakashandisa nano Cu2O photocatalytic degradation yemethylene bhuruu, nezvimwewo, uye yakawana mhedzisiro yakanaka.
Mumakore achangopfuura,cuprous oxide nanoparticlesyakashandiswa zvakanyanya mukurapa kwemvura yetsvina uye tekinoroji yekuchenesa.Zvichienzaniswa nemamwe matekinoroji ekuchenesa mvura echinyakare, vane zvakanakira kushanda kwakakwirira, mutengo wakaderera, kugadzikana uye kushandisa chiedza chezuva, uye vane tarisiro yakanaka uye yakakura.TiO2inowanzoshandiswa kuchenesa tsvina nechiedza chezuva.Nekudaro, chinhu ichi chinoda ultraviolet activation uye ine zvakawanda zvinokanganisa.Naizvozvo, chiedza chinooneka sechiedza chesimba sosi yekuchenesa tsvina yakagara iri chinangwa chinoteverwa nemasayendisiti.
Guangzhou Hongwu Material Technology Co., Ltd. ine kwenguva yakareba yakagadzika kupihwa kwe cuprous oxide (Cu2O) nanoparticles mumabhechi ane fekitori kutengesa zvakananga, kuvimbiswa kwemhando, uye mutengo wakanaka.Hongwu Nano anotarisira kushanda newe.
