The utilization of biomass sugars has received great interesting recently. Herein, we present a highly efficient hybrid solar biomass fuel cell that utilizes thermal‐ and photocatalysis of solar irradiation and converts biomass sugars into electricity with high power output. The fuel cell uses polyoxometalates (POMs) as photocatalyst to decompose sugars and capture their electrons. The reduced POMs have strong visible and near‐infrared light adsorption, which can significantly increase the temperature of the reaction system and largely promotes the thermal oxidation of sugars by the POM. In addition, the reduced POM functions as charge carrier that can release electrons at the anode in the fuel cell to generate electricity. The electron‐transfer rates from glucose to POM under thermal and light‐irradiation conditions were investigated in detail. The power outputs of this solar biomass fuel cell are investigated by using different types of sugars as fuels, with the highest power density reaching 45 mW cm⁻².

糖驱动的高效生物质燃料电池，通过太阳辐照进行光催化和热催化

近来，生物质糖的利用已经引起了极大的兴趣。本文中，我们介绍了一种高效的混合太阳能生物质燃料电池，该电池利用了太阳辐射的热催化和光催化作用，并将生物质糖转化为具有高功率输出的电能。燃料电池使用多金属氧酸盐（POM）作为光催化剂来分解糖并捕获其电子。还原的POM具有很强的可见光和近红外光吸附能力，这可以显着提高反应系统的温度，并在很大程度上促进POM对糖的热氧化。另外，还原的POM用作电荷载体，其可以在燃料电池中的阳极处释放电子以发电。详细研究了在热和光辐照条件下从葡萄糖到POM的电子转移速率。⁻²。
