Carbon dioxide (CO) is a problematic greenhouse gas, although its conversion to alternative fuels represents a promising approach to limit its long-term effects. Here, pyroelectric nanostructured materials are shown to utilize temperature-variations and to reduce CO for methanol. Layered perovskite bismuth tungstate nanoplates harvest heat energy from temperature-variation, driving pyroelectric catalytic CO reduction for methanol at temperatures between 15 °C and 70 °C. The methanol yield can be as high as 55.0 μmol⋅g after experiencing 20 cycles of temperature-variation. This efficient, cost-effective, and environmental-friendly pyroelectric catalytic CO reduction route provides an avenue towards utilizing natural diurnal temperature-variation for future methanol economy.
二氧化碳（CO）是一种有问题的温室气体，尽管将其转化为替代燃料是限制其长期影响的一种有前景的方法。在此，热释电纳米结构材料被证明可利用温度变化并将CO还原为甲醇。层状钙钛矿钨酸铋纳米板从温度变化中获取热能，在15°C至70°C的温度下驱动热释电催化CO还原为甲醇。经过20个温度变化循环后，甲醇产量可达55.0 μmol⋅g。这种高效、经济且环保的热释电催化CO还原途径为利用自然昼夜温度变化实现未来甲醇经济提供了一条途径。
