據哈工大新聞網報道：在zai國guo家jia傑jie出chu青qing年nian基ji金jin和he城cheng市shi水shui資zi源yuan與yu水shui環huan境jing國guo家jia重zhong點dian實shi驗yan室shi課ke題ti的de資zi助zhu下xia，哈ha工gong大da馮feng玉yu傑jie教jiao授shou課ke題ti組zu在zai光guang催cui化hua燃ran料liao電dian池chi方fang麵mian取qu得de重zhong要yao進jin展zhan。該gai課ke題ti組zu的de研yan究jiu成cheng果guo《一種實現同步電能回收和汙染物去除的生物陰極耦合光催化燃料電池》最近發表於環境領域著名國際期刊《環境科學與技術》上（影響因子5.48）。該論文的新穎性和重要性得到審稿人充分肯定，被期刊選為亮點文章重點推薦，哈工大為該文章的唯一署名單位。相xiang關guan研yan究jiu表biao明ming，當dang能neng量liang大da於yu或huo等deng於yu禁jin帶dai寬kuan度du的de光guang照zhao射she到dao半ban導dao體ti光guang催cui化hua劑ji表biao麵mian時shi，其qi導dao帶dai和he價jia帶dai分fen別bie產chan生sheng光guang生sheng電dian子zi和he光guang生sheng空kong穴xue，其qi中zhong空kong穴xue是shi強qiang氧yang化hua劑ji，可ke以yi氧yang化hua幾ji乎hu所suo有you有you機ji物wu，而er光guang生sheng電dian子zi是shi強qiang還hai原yuan劑ji，可ke以yi通tong過guo外wai電dian路lu傳chuan遞di到dao陰yin極ji。光guang催cui化hua燃ran料liao電dian池chi就jiu是shi基ji於yu光guang催cui化hua材cai料liao的de光guang電dian轉zhuan化hua特te性xing，同tong步bu實shi現xian汙wu染ran物wu的de降jiang解jie和he電dian能neng回hui收shou的de裝zhuang置zhi。通tong常chang為wei了le獲huo得de較jiao高gao的de空kong穴xue/電子分離效率，陰極催化劑多選用貴金屬催化劑或過渡金屬催化劑，這類催化劑價格昂貴，催化性能也容易因使用過程中的催化劑團聚、流失、中毒等降低，使用壽命較短。 fengyujiejiaoshouketizudupiqijing，jiangjuyoudianhuaxuehuoxingdehaoyangshengwumozuoweiyinjicuihuaji，goujianlexinyingdeshengwuyinjiouheguangcuihuaranliaodianchixitong。gaihaoyangshengwuyinjikeyicongfeishuizhongfujidedao，bingyiwuranwuweiyingyangwuzhizengzhi，zaishengchangdaixiedetongshicuihuayinjifanying，juyoulianjia、穩定、可ke再zai生sheng的de特te點dian，而er且qie利li用yong微wei生sheng物wu的de代dai謝xie過guo程cheng實shi現xian汙wu染ran物wu質zhi的de轉zhuan化hua和he去qu除chu。與yu此ci同tong時shi，該gai課ke題ti組zu在zai研yan究jiu過guo程cheng中zhong還hai首shou次ci發fa現xian，光guang電dian路lu的de介jie入ru，可ke以yi有you效xiao提ti高gao微wei生sheng物wu催cui化hua燃ran料liao電dian池chi陰yin極ji點dian位wei，從cong而er使shi得de陽yang極ji生sheng物wu催cui化hua效xiao率lv提ti高gao近jin兩liang倍bei，為wei該gai技ji術shu應ying用yong於yu生sheng物wu難nan降jiang解jie物wu質zhi的de轉zhuan化hua提ti供gong了le又you一yi新xin思si路lu。此(ci)外(wai)，課(ke)題(ti)組(zu)經(jing)研(yan)究(jiu)發(fa)現(xian)，同(tong)時(shi)發(fa)生(sheng)的(de)微(wei)生(sheng)物(wu)代(dai)謝(xie)過(guo)程(cheng)與(yu)陰(yin)極(ji)催(cui)化(hua)過(guo)程(cheng)之(zhi)間(jian)存(cun)在(zai)著(zhe)複(fu)雜(za)的(de)關(guan)係(xi)，生(sheng)物(wu)陰(yin)極(ji)的(de)催(cui)化(hua)活(huo)性(xing)受(shou)到(dao)微(wei)生(sheng)物(wu)代(dai)謝(xie)活(huo)性(xing)的(de)製(zhi)約(yue)，同(tong)時(shi)又(you)對(dui)代(dai)謝(xie)過(guo)程(cheng)有(you)一(yi)定(ding)的(de)反(fan)作(zuo)用(yong)，這(zhe)表(biao)明(ming)微(wei)生(sheng)物(wu)可(ke)能(neng)利(li)用(yong)胞(bao)外(wai)電(dian)子(zi)為(wei)能(neng)量(liang)來(lai)源(yuan)進(jin)行(xing)生(sheng)長(chang)代(dai)謝(xie)。目(mu)前(qian)，課(ke)題(ti)組(zu)正(zheng)在(zai)對(dui)生(sheng)物(wu)陰(yin)極(ji)催(cui)化(hua)機(ji)製(zhi)展(zhan)開(kai)深(shen)入(ru)研(yan)究(jiu)。
