Electrocatalytic nitrate reduction reaction has attracted increasing attention due to its goal of low carbon emission and environmental ***,we report an efficient NitRR catalyst composed of single Mn sites with atomically dispersed oxygen(O)coordination on bacterial cellulose-converted graphitic carbon(Mn-O-C).Evidence of the atomically dispersed Mn-(O-C_(2))_(4)moieties embedding in the exposed basal plane of carbon surface is confirmed by X-ray absorption *** a result,the as-synthesized Mn-O-C catalyst exhibits superior NitRR activity with an NH_(3)yield rate(RNH_(3))of 1476.9±62.6μg h^(−1)cm^(−2)at−0.7 V(*** hydrogen electrode,RHE)and a faradaic efficiency(FE)of 89.0±3.8%at−0.5 V(***)under ambient ***,when evaluated with a practical flow cell,Mn-O-C shows a high RNH_(3)of 3706.7±552.0μg h^(−1)cm^(−2)at a current density of 100 mA cm−2,2.5 times of that in the H *** in situ FT-IR and Raman spectroscopic studies combined with theoretical calculations indicate that the Mn-(O-C_(2))_(4)sites not only effectively inhibit the competitive hydrogen evolution reaction,but also greatly promote the adsorption and activation of nitrate(NO_(3)^(−)),thus boosting both the FE and selectivity of NH_(3)over Mn-(O-C_(2))_(4)sites.

采用浸渍法制备了SBA-15分子筛负载对甲苯磺酸(TsOH)催化剂TsOH/SBA-15,探究了其催化α-甲基苯乙烯(α-MS)和异丙苯过氧化氢(CHP)反应制备过氧化二异丙苯(DCP)的活性,并对反应过程进行了模拟分析.当进料比n(α-甲基苯乙烯)/n(异丙苯过氧化氢)=2.0, TsOH/SBA-15用量为CHP质量的0.15%,于44℃反应2.5h, DCP的产率为62.1%.模拟计算结果表明,反应过程有异步协同反应和分步反应两种机理,在异步协同反应中α-MS, CHP和TsOH只需要经过一个过渡态即可完成,而分步反应中反应物需要经过两个过渡态以及一个中间体才能完成,两种路径均涉及2次H^(+)的转移.在44℃下,异步协同反应的反应能垒(Δg)为121.8 kJ/mol,分步反应中两个过渡态对应的反应能垒分别为74.1和78.3 kJ/mol.
