Efficient Biomass Fuel Cell Powered by Sugar with Photo‐ and Thermal‐Catalysis by Solar Irradiation

Abstract

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 .

Desenvolvimento de fotocélulas de glicose/H2O2 usando fotoanodos à base de W-BiVO4/V2O5 para geração de eletricidade

“…Por outro lado, é relatado que os efeitos da utilização de açúcares, como a glicose, nas PFC ainda não são claros em comparação ao metanol, etanol e glicerol, que são os combustíveis mais comuns utilizados nos experimentos (BHUNIA; DUTTA, 2020). Estudos recentes têm relatado também a utilização de glicose em células eletroquímicas foto e termocatalisadas, utilizando polioxometalatos como eletrólitos, eletrodos de grafite em operação sob temperaturas de até 60 ºC(LIU et al, 2018). Outras pesquisas recentes têm utilizado Glc como combustível e BiVO4 como fotoanodo em PFC, com resultados promissores(ZHANG et al, 2015(ZHANG et al, , 2017, conseguindo aumento da fotocorrente e, em consequência, uma melhora dos parâmetros de desempenho das PFC devido ao efeito de duplicação de corrente.…”
