據http:// fuelcellsworks.com報道：美mei國guo能neng源yuan部bu阿e貢gong實shi驗yan室shi的de研yan究jiu人ren員yuan研yan製zhi了le一yi套tao微wei型xing氫qing氣qi發fa生sheng裝zhuang置zhi，研yan究jiu人ren員yuan利li用yong石shi墨mo烯xi碳tan原yuan子zi之zhi間jian的de鏈lian結jie構gou可ke以yi把ba電dian子zi轉zhuan移yi到dao其qi他ta物wu質zhi上shang的de特te性xing，使shi用yong光guang能neng製zhi氫qing。據ju悉xi，該gai氫qing氣qi發fa生sheng器qi的de尺chi寸cun非fei常chang小xiao，比bi蜘zhi蛛zhu絲si的de直zhi徑jing還hai要yao小xiao。眾zhong所suo周zhou知zhi，氫qing元yuan素su在zai地di球qiu上shang廣guang泛fan存cun在zai，但dan氫qing元yuan素su通tong常chang與yu其qi他ta元yuan素su結jie合he。如ru今jin工gong業ye上shang利li用yong天tian然ran氣qi與yu高gao溫wen的de蒸zheng汽qi反fan應ying，使shi得de氫qing原yuan子zi脫tuo離li，製zhi取qu氫qing氣qi。但dan這zhe一yi過guo程cheng伴ban隨sui著zhe溫wen室shi氣qi體ti二er氧yang化hua碳tan的de生sheng成cheng。阿e貢gong實shi驗yan室shi成cheng功gong研yan發fa的de微wei型xing氫qing氣qi發fa生sheng器qi，使shi得de製zhi氫qing過guo程cheng中zhong不bu產chan生sheng二er氧yang化hua碳tan。在早期的研究中，研究人員發現一些單細胞生物會使用一種BR蛋dan白bai來lai吸xi收shou太tai陽yang光guang，並bing且qie產chan生sheng質zhi子zi，通tong過guo膜mo輸shu送song到dao內nei部bu，以yi產chan生sheng化hua學xue能neng。研yan究jiu人ren員yuan嚐chang試shi使shi用yong該gai蛋dan白bai與yu鈦tai的de氧yang化hua物wu結jie合he，吸xi收shou紫zi外wai線xian，把ba水shui分fen解jie為wei氫qing氣qi與yu氧yang氣qi。但dan是shi紫zi外wai光guang僅jin僅jin占zhan太tai陽yang光guang譜pu的de4%，想提高製氫量，必須使用全部可見光的能量。 weiletigaoqingqifashengqidezhiqingliang，yanjiurenyuanzhaodaoleshimoxizhezhongxinxingcailiao。shimoxinengtigongzugoudebiaomianji，shidedianzikuaisuyidong，jiakuaidianzichuanshuxiaolv。yucitongshi，shimoxipingtaikeyibaochidanbaizhidehuoxing，zuoweidanbaizhiyutaideyanghuawulianjiedeqiaoliang。ciwai，yanjiurenyuanhaiduitaideyanghuawujinxinggaixing，shideqiduikejianguangmingan。zhuangzhizhengchangyunxingshi，BR蛋白接收到可見光後，反應生成的電子通過石墨烯傳遞到鈦合金上。而在太陽光綠光帶能量的驅動下，質子沿著BRdanbaidemochuandi，zuihoudaodataihejinbiaomiandebonamikelishang。cishizhiziyudianzijieheshengchengqingqi。yanjiurenyuanbiaoshi，gaiweixingzhiqingzhuangzhiyidandaguimoshengchan，yiweizherihouqichejiunengshiyongqingqituidong，ranshaodeweiyichanwushishui，zhejiangbaituowenshiqitidekunrao。
