We aimed to construct a method involving the photocatalytic oxidative dehydrogenation of formic acid (FA) to promote the acetone reductive hydrogenation of C–C coupling, where photo-electrons and photo-holes could be effectively used. The results showed that the conversion rates of acetone and FA in the g-C₃N₄ photocatalytic acetone–FA coupling reaction system were 88.74% and 60.82%, respectively. Further research showed that the Na⁺ concentration on the surface of the C₃N₄ photocatalyst was also positively correlated with pinacol selectivity. The g-C₃N₄ treated with 5 M NaOH showed a high pinacol selectivity of 60.87%, which was increased by 32.30%.

在NaOH处理的g-C3N4光催化剂上，通过甲酸脱氢，促进丙酮CC的加氢反应生成频哪醇

我们旨在构建一种涉及甲酸（FA）的光催化氧化脱氢的方法，以促进C-C偶合的丙酮还原氢化，其中可有效利用光电子和光孔。结果表明，在gC ₃ N ₄光催化丙酮－FA偶联反应体系中，丙酮和FA的转化率分别为88.74％和60.82％。进一步的研究表明，C ₃ N ₄光催化剂表面的Na ⁺浓度也与频哪醇选择性正相关。用5 M NaOH处理的gC ₃ N ₄显示出较高的频哪醇选择性为60.87％，增加了32.30％。
