如果开发出直接将二氧化碳用作原料的高效和可再生工艺，二氧化碳可能成为化学品和燃料的来源。它的两种还原产物是甲酸和甲醇，这两种物质也被认为是可持续储氢的液体有机化学载体。本文报道了二氧化碳加氢制甲酸和甲酸歧化制甲醇都可以在常温和酸性水溶液中，用Ir催化剂实现。在无添加剂的水中甲酸的产率最高，而酸化导致甲酸完全歧化(98 %)和选择性歧化(96 %)生成甲醇。这些有希望的特点，再加上反应温度低，没有有机溶剂和添加剂，对于可持续的氢/甲醇经济是相关的。
Carbon dioxide may constitute a source of chemicals and fuels if efficient and renewable processes are developed that directly utilize it as feedstock. Two of its reduction products are formic acid and methanol, which have also been proposed as liquid organic chemical carriers in sustainable hydrogen storage. Here we report that both the hydrogenation of carbon dioxide to formic acid and the disproportionation of formic acid into methanol can be realized at ambient temperature and in aqueous, acidic solution, with an iridium catalyst. The formic acid yield is maximized in water without additives, while acidification results in complete (98 %) and selective (96 %) formic acid disproportionation into methanol. These promising features in combination with the low reaction temperatures and the absence of organic solvents and additives are relevant for a sustainable hydrogen/methanol economy.
