Special Issue Information

Dear Colleagues,

The field of photoelectrochemistry is a rapidly advancing scientific discipline that harnesses the power of light energy to convert chemical energy. It holds great promise in the areas of renewable energy and environmental conservation. Photoelectrochemistry finds applications in diverse fields such as solar energy conversion, environmental remediation, and hydrogen production through water splitting. The key to achieving efficient and sustainable solar energy conversion and other photo-driven chemical processes lies in the development of advanced materials that optimize light absorption, charge separation, and catalytic activity.

This Special Issue, entitled “Advanced Materials in Photoelectrochemistry” will explore and present the latest research findings, innovations, and breakthroughs in the design, synthesis, characterization, and application of advanced materials for photoelectrochemistry. We welcome original research articles and reviews that cover a wide range of topics, including:

  • Novel materials for photoelectrochemical applications, such as photovoltaic devices for water splitting and environmental remediation.
  • Synthesis and fabrication techniques for advanced photoelectrode materials, including photocatalysts, electrocatalysts, semiconductors, quantum dots, perovskites, carbon-based nanomaterials, and more.
  • Fundamental principles and mechanisms underlying photoelectrochemical processes.
  • Emerging applications and technological advancements in the field of photoelectrochemistry.

By shedding light on these areas, we hope to foster the exchange of knowledge, inspire further research, and contribute to the advancement of photoelectrochemistry and its potential in addressing global energy and environmental challenges.

The photoelectrochemical (PEC) conversion of organic small molecules offers a dual benefit of synthesizing value-added chemicals and concurrently producing hydrogen (H2). Ethylene glycol, with its dual hydroxyl groups, stands out as a versatile organic substrate capable of yielding various C1 and C2 chemicals. In this study, we demonstrate that pH modulation markedly enhances the photocurrent of BiVO4 photoanodes, thus facilitating the efficient oxidation of ethylene glycol while simultaneously generating H2. Our findings reveal that in a pH = 1 ethylene glycol solution, the photocurrent density at 1.23 V vs. RHE can attain an impressive 7.1 mA cm−2, significantly surpassing the outputs in neutral and highly alkaline environments. The increase in photocurrent is attributed to the augmented adsorption of ethylene glycol on BiVO4 under acidic conditions, which in turn elevates the activity of the oxidation reaction, culminating in the maximal production of formic acid. This investigation sheds light on the pivotal role of electrolyte pH in the PEC oxidation process and underscores the potential of the PEC strategy for biomass valorization into value-added products alongside H2 fuel generation.
