Nrog rau kev sib kis thoob ntiaj teb tsis tu ncua, huab cua huv huv thiab tshuaj tua kab mob tau dhau los ua qhov tseem ceeb rau kev tswj hwm ib puag ncig kev noj qab haus huv. Txhawm rau daws qhov teeb meem no, photocatalytic thev naus laus zis tau saib xyuas vim nws lub peev xwm los tshem tawm cov pa phem thiab tua cov kab mob phem thiab kab mob.
Ob lub wavelengths tshwj xeeb ntawm lub teeb, 365nm thiab 385nm, tuaj yeem siv los txhawb cov photocatalysts rau huab cua purification thiab tshuaj tua kab mob. Photocatalysts yog cov ntaub ntawv uas, thaum txhawb los ntawm cov wavelengths, tuaj yeem rhuav tshem cov pa phem thiab tua cov kab mob los ntawm oxidation thiab txo cov tshuaj tiv thaiv. Cov wavelengths no nyob rau hauv lub ultraviolet (UV) ntau yam thiab muaj peev xwm ua puas DNA thiab cellular qauv ntawm cov kab mob, ua rau lawv tuag.
Cov txheej txheem photocatalytic tau raug pov thawj los ua kom cov pa phem hauv cov organic xws li volatile organic compounds (VOCs), formaldehyde, thiab txawm tias muaj ntxhiab tsw. Tsis tas li ntawd, photocatalysts tuaj yeem pab tshem tawm cov khoom phom sij, suav nrog nitrogen oxides (NOx) thiab carbon monoxide (CO), feem ntau pom nyob rau hauv lub tsheb tso tsheb thiab kev lag luam emissions.
Tsis tas li ntawd, photocatalytic thev naus laus zis tau siv los daws qhov kev kis thoob qhov txhia chaw tam sim no los ntawm deactivating SARS-CoV-2, tus kab mob uas ua rau COVID-19. Photocatalysts uas muaj nyiaj thiab titanium dioxide tau pom tias tua tus kab mob zoo li ntawm 30 feeb ntawm kev raug UV teeb.
Hauv kev xaus, siv 365nm thiab 385nm wavelengths los txhawb cov photocatalysts rau huab cua purification thiab tshuaj tua kab mob yog ib qho kev cog lus technology rau kev txhim kho huab cua hauv tsev thiab txhawb kev noj qab haus huv rau pej xeem. Los ntawm kev txo cov pa phem hauv huab cua thiab tua cov kab mob tsis zoo, lub tshuab no tuaj yeem tsim kom muaj kev nyab xeeb dua rau tib neeg nyob, ua haujlwm, thiab ua si.
