Abstract
This study explores a novel photoelectrode composed of copper oxide (CuO), polyaniline (PANI), and gold (Au) for efficient hydrogen production through photoelectrochemical (PEC) water splitting. Structural and morphological analyses using various techniques confirm the successful fabrication of the ternary Au/PANI/CuO photoelectrode. The integration of Au, PANI, and CuO nanomaterials enhances light harvesting, facilitates charge transfer, and reduces charge recombination due to the plasmonic effect of Au and the synergistic interaction between PANI and CuO. The Au/PANI/CuO photoelectrode achieves a 300-fold increase in photocurrent density (15 mA cm−2 at −0.39 V vs. RHE) compared to pure CuO. Additionally, it demonstrates superior operational stability for 5 hours and records an IPCE of 45% at 500 nm. These findings pave the way for the development of high-performance and durable plasmonic/polymer/semiconductor photoelectrodes for sustainable and clean hydrogen generation.
本研究探索了一种由氧化铜(CuO)、聚苯胺(PANI)和金(Au)组成的新型光电极,用于通过光电化学(PEC)水分解高效制氢。利用各种技术对Au/PANI/CuO三元光电极进行了结构和形态分析,证实了该电极的成功制备。Au, PANI和CuO纳米材料的集成增强了光捕获,促进了电荷转移,并减少了由于Au的等离子体效应和PANI与CuO之间的协同相互作用而产生的电荷重组。与纯CuO相比,Au/PANI/CuO光电极的光电流密度增加了300倍(在-0.39 V与RHE下为15 mA cm-2)。此外,它在5小时内表现出卓越的运行稳定性,并在500纳米处记录了45%的IPCE。这些发现为开发高性能和耐用的等离子体/聚合物/半导体光电极铺平了道路,用于可持续和清洁的制氢。
期刊介绍:
Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions.
The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
