Nitrite ions are shown to have significant influence on the selectivity of the photocatalytic oxidation of methane to methanol. An almost complete inhibition of undesired CO2 has been achieved with BiVO4 in the presence of a low concentration of nitrite, which might act both as a UV filter and as a hydroxyl radical scavenger.
结果表明,亚硝酸根离子对甲烷光催化氧化制甲醇的选择性有显著影响。在低浓度亚硝酸根存在的情况下,BiVO4几乎完全抑制了不需要的CO2生成,亚硝酸根可能同时起到紫外线过滤器和羟基自由基清除剂的作用。
