　　合成電(dian)化(hua)學(xue)(xue)(xue)(xue)新(xin)技術(shu)(shu)是國際純粹與應用化(hua)學(xue)(xue)(xue)(xue)聯(lian)合會(IUPAC)評定的(de)(de)2023年度(du)(du)化(hua)學(xue)(xue)(xue)(xue)領域十大新(xin)興技術(shu)(shu)之一(yi)。因為其(qi)具備綠色(se)、安全(quan)和(he)(he)低能(neng)(neng)耗的(de)(de)特(te)性(xing)，合成電(dian)化(hua)學(xue)(xue)(xue)(xue)新(xin)技術(shu)(shu)將有望發展成為新(xin)質(zhi)生產力(li)，用于(yu)解決當前(qian)基于(yu)化(hua)石(shi)能(neng)(neng)源驅動的(de)(de)現行(xing)生產力(li)產生的(de)(de)環境污(wu)染、安全(quan)生產風險和(he)(he)高(gao)能(neng)(neng)耗問題(ti)。這種新(xin)興合成技術(shu)(shu)主要以(yi)直流(liu)電(dian)(DC)作為驅動力(li)，并(bing)通過調節電(dian)流(liu)或(huo)者電(dian)壓控制化(hua)學(xue)(xue)(xue)(xue)反(fan)應過程。交流(liu)電(dian)(AC)具有極性(xing)反(fan)轉和(he)(he)周(zhou)期性(xing)波動的(de)(de)特(te)點(dian)，并(bing)且(qie)具備如波形(xing)、頻(pin)率、占空比(bi)等更多可調節電(dian)學(xue)(xue)(xue)(xue)參數(shu)的(de)(de)優勢，為實(shi)現精準(zhun)物質(zhi)制造提(ti)供“無限潛力(li)”。然而，更多維度(du)(du)的(de)(de)電(dian)學(xue)(xue)(xue)(xue)參數(shu)引入電(dian)化(hua)學(xue)(xue)(xue)(xue)合成反(fan)應中會導(dao)致可優化(hua)的(de)(de)反(fan)應條件呈指數(shu)級(ji)增(zeng)加，極大增(zeng)加了研究(jiu)難(nan)度(du)(du)。因此至今為止交流(liu)電(dian)合成技術(shu)(shu)仍然處(chu)于(yu)萌芽階段，僅(jin)有數(shu)例簡(jian)單應用研究(jiu)見諸報道。

　　雷(lei)愛(ai)文(wen)(wen)教授團(tuan)隊耕耘綠色合成化(hua)(hua)(hua)(hua)(hua)(hua)學(xue)超過15年，本項研究首(shou)創開(kai)發了可編(bian)程波形(xing)交(jiao)(jiao)流(liu)電(pAC)合成技術(shu)，實現(xian)了銅(tong)(tong)催(cui)化(hua)(hua)(hua)(hua)(hua)(hua)的放氫氣氧化(hua)(hua)(hua)(hua)(hua)(hua)交(jiao)(jiao)叉偶聯(lian)(lian)(lian)反(fan)應(ying)。通過對交(jiao)(jiao)流(liu)電波形(xing)的電學(xue)參數(頻率、電流(liu)和(he)占空比)進行(xing)程序編(bian)輯(ji)可得到定(ding)制化(hua)(hua)(hua)(hua)(hua)(hua)的交(jiao)(jiao)流(liu)電信(xin)(xin)號(hao)。不同編(bian)輯(ji)模(mo)式的電信(xin)(xin)號(hao)不僅促進了電解條件下(xia)銅(tong)(tong)催(cui)化(hua)(hua)(hua)(hua)(hua)(hua)劑(ji)循環(huan)再生，而且分別精準(zhun)調(diao)控銅(tong)(tong)催(cui)化(hua)(hua)(hua)(hua)(hua)(hua)劑(ji)形(xing)成“銅(tong)(tong)結合碳自由基物種(zhong)”和(he)“碳-銅(tong)(tong)活(huo)性物種(zhong)”。另外，雷(lei)愛(ai)文(wen)(wen)教授團(tuan)隊開(kai)發了原位電子順磁共振波譜-交(jiao)(jiao)流(liu)電解聯(lian)(lian)(lian)用表(biao)征技術(shu)，首(shou)次觀測(ce)到不同交(jiao)(jiao)流(liu)電信(xin)(xin)號(hao)動態調(diao)控銅(tong)(tong)催(cui)化(hua)(hua)(hua)(hua)(hua)(hua)物種(zhong)活(huo)性的變化(hua)(hua)(hua)(hua)(hua)(hua)規律。基于(yu)可編(bian)程交(jiao)(jiao)流(liu)電合成技術(shu)，研究團(tuan)隊成功實現(xian)了銅(tong)(tong)催(cui)化(hua)(hua)(hua)(hua)(hua)(hua)活(huo)化(hua)(hua)(hua)(hua)(hua)(hua)烷烴(jing)直(zhi)接碳氫鍵氧化(hua)(hua)(hua)(hua)(hua)(hua)偶聯(lian)(lian)(lian)反(fan)應(ying)和(he)氧化(hua)(hua)(hua)(hua)(hua)(hua)雙官能團(tuan)化(hua)(hua)(hua)(hua)(hua)(hua)反(fan)應(ying)，而這兩(liang)類(lei)反(fan)應(ying)在傳統氧化(hua)(hua)(hua)(hua)(hua)(hua)劑(ji)條件和(he)直(zhi)流(liu)電氧化(hua)(hua)(hua)(hua)(hua)(hua)條件下(xia)均表(biao)現(xian)出較差(cha)的反(fan)應(ying)性。

　　此項研(yan)究實現了交流(liu)電(dian)解(jie)環境下金屬(shu)催(cui)化(hua)物種(zhong)精準調控，解(jie)決了電(dian)合(he)成(cheng)條件(jian)下過渡(du)金屬(shu)催(cui)化(hua)劑容易在(zai)陰極析(xi)出失活而(er)必須用分離池(chi)的問題。此項研(yan)究為(wei)一(yi)體式電(dian)解(jie)池(chi)條件(jian)下，金屬(shu)催(cui)化(hua)耦合(he)電(dian)催(cui)化(hua)發展(zhan)新型合(he)成(cheng)反應(ying)提供(gong)(gong)可行路徑。可編程波(bo)形(xing)交流(liu)電(dian)合(he)成(cheng)技(ji)術的出現，將為(wei)合(he)成(cheng)電(dian)化(hua)學新技(ji)術在(zai)綠色物質制造等更廣泛應(ying)用領域提供(gong)(gong)極大助力，為(wei)化(hua)學化(hua)工綠色化(hua)，智能化(hua)和高端(duan)化(hua)提供(gong)(gong)新的動能。
