Special Issue Information

Dear Colleagues,

Heterogeneous photocatalysts that are based on nanocomposites have gained significant attention in recent years due to their potential applications in various fields, such as environmental remediation, solar energy conversion, and water purification. The combination of different nanomaterials can create heterojunctions that enhance the photocatalytic properties of the composite and promote the separation of photoinduced charge carriers.

Nanocomposites-based photocatalysts can be synthesized using different methods, and their properties can be modified by adjusting the synthesis parameters, such as the nanoparticle size, shape, surface area, and composition. One of the main advantages of using photocatalysts is that they offer a green route for environmental pollution remediation. A wide range of pollutants can be effectively degraded by photocatalysts. Overall, heterogeneous photocatalysts based on nanocomposites have numerous benefits, including easy synthesis, tunable characteristics, and excellent photocatalytic performance. They have great potential to be used in various fields for solving environmental and energy-related issues.

This special issue welcomes submissions of original research-based articles and reviews that describe the manufacturing process, analytical description, and applications of photocatalysts based on nanocomposites.

Abstract

Nowadays, the efficient conversion of plant biomass components (alcohols, carbohydrates, etc.) into more energy-intensive fuels, such as hydrogen, is one of the urgent scientific and technological problems. The present study is the first one focused on the photoinduced hydrogen evolution from aqueous D-glucose and D-xylose using layered perovskite-like oxides HCa₂Nb₃O₁₀, H₂La₂Ti₃O₁₀, and their organically modified derivatives that have previously proven themselves as highly active photocatalysts. The photocatalytic performance was investigated for the bare compounds and products of their surface modification with a 1 mass. % Pt cocatalyst. The photocatalytic experiments followed an innovative scheme including dark stages as well as the control of the reaction suspension’s pH and composition. The study has revealed that the inorganic−organic derivatives of the layered perovskite-like oxides can provide efficient conversion of carbohydrates into hydrogen fuel, being up to 8.3 times more active than the unmodified materials and reaching apparent quantum efficiency of 8.8%. Based on new and previously obtained data, it was shown that the oxides’ interlayer space functions as an additional reaction zone in the photocatalytic hydrogen production and the contribution of this zone to the overall activity is dependent on the steric characteristics of the sacrificial agent used.

Abstract

Photoelectrochemical cells (PECs) are an important technology for converting solar energy, which has experienced rapid development in recent decades. Transparent conductive oxides (TCOs) are also gaining increasing attention due to their crucial role in PEC reactions. This review comprehensively delves into the significance of TCO materials in PEC devices. Starting from an in-depth analysis of various TCO materials, this review discusses the properties, fabrication techniques, and challenges associated with these TCO materials. Next, we highlight several cost-effective, simple, and environmentally friendly methods, such as element doping, plasma treatment, hot isostatic pressing, and carbon nanotube modification, to enhance the transparency and conductivity of TCO materials. Despite significant progress in the development of TCO materials for PEC applications, we at last point out that the future research should focus on enhancing transparency and conductivity, formulating advanced theories to understand structure–property relationships, and integrating multiple modification strategies to further improve the performance of TCO materials in PEC devices.
