Abstract

Effectively managing the environmental burden of plastic pollution while simultaneously meeting global energy demands necessitates the development of innovative technological and systemic solutions. Herein, we present a photoelectrocatalytic system that upcycles polyethylene terephthalate (PET) waste into formate while co-producing hydrogen fuel using a bifunctional boron-doped NiMoO₄/Ni(OH)₂ on nickel foam, denoted BNN@NF. The BNN@NF catalyst achieves exceptional catalytic performance with a low overpotential of 48 mV at 10 mA cm^-2 for HER and a Faradaic efficiency of 94.6% for the oxidation of PET-derived hydrolysate into formate. In-situ mechanical analysis reveals that the enhanced catalytic performance of BNN@NF is attributed to the superhydrophilic surface accelerating HER kinetics and the highly exposed Ni³⁺ species for C-C cleavage of ethylene glycol into formate. By integrating BNN@NF with a perovskite solar cell in a wireless "artificial leaf" configuration, we demonstrate simultaneous production of H₂ (985 µmol cm^-2 h^-1) and formate (42 µmol cm^-2 h^-1) without external bias. This work introduces a solar-driven pathway to upcycle waste plastics into value-added products, bridging environmental remediation and renewable energy storage.

钙钛矿驱动的PET废料太阳能重整及同步制氢

有效管理塑料污染的环境负担，同时满足全球能源需求，需要开发创新技术和系统解决方案。在此，我们提出了一种光电催化系统，该系统将聚对苯二甲酸乙二醇酯（PET）废物升级为甲酸盐，同时在泡沫镍上使用双功能掺硼NiMoO4/Ni(OH)2共同生产氢燃料，标记为BNN@NF。BNN@NF催化剂具有优异的催化性能，在10 mA cm-2下，HER的过电位低至48 mV，将pet衍生的水解产物氧化成甲酸盐的法拉第效率为94.6%。原位力学分析表明，BNN@NF催化性能的增强是由于超亲水性表面加速了HER动力学和高暴露的Ni3+物质对乙二醇C-C裂解成甲酸酯的催化作用。通过将BNN@NF与钙钛矿太阳能电池集成在无线“人造叶子”结构中，我们展示了同时生产H2（985µmol cm-2 h-1）和甲酸（42µmol cm-2 h-1）而没有外部偏置。这项工作介绍了一种太阳能驱动的途径，将废塑料升级为增值产品，连接环境修复和可再生能源储存。
