• Synergy of Photogenerated Electrons and Holes toward Efficient Photocatalytic Urea Synthesis from CO2 and N2 (2024) · Angewandte Chemie International Edition · cited 101× · doi

  Abstract Directly coupling N 2 and CO 2 to synthesize urea by photocatalysis paves a sustainable route for urea synthesis, but its performance is limited by the competition of photogenerated electrons between N 2 and CO 2 , as well as the underutilized photogenerated holes.

• Assessment of Solar‐to‐Fuels Strategies: Photocatalysis and Electrocatalytic Reduction (2016) · Energy Technology · cited 35× · doi

  For the photocatalytic process, the most important challenge is to improve the solar‐to‐fuels efficiency to at least 15 %, whereas for the electrocatalytic reduction process, even with much improved current density, cell potential, and reaction selectivity, the process will be ultimately limited by the price of solar (or other renewable) electricity.

• Sustainable Fabrication of Ag2O-Doped Anatase TiO2 Nanoparticles via Green Synthesis for Enhanced Photocatalysis (2026) · Journal of Applied Materials and Technology · doi

  The development of environmentally friendly synthesis routes for photocatalytic materials is a growing area of research. The scalability and cost-effectiveness of the synthesis route are crucial factors for industrial applications. The stability and durability of the developed nanoparticles under various environmental conditions need to be evaluated.

• A review: recent progress of piezoelectric effect coupled photocatalytic reaction: diverse mechanisms, system/structure design, characterization and application (2026) · Catal · doi

  The commercial application of traditional photocatalytic materials remains limited by core challenges such as the rapid recombination of photogenerated electron-hole pairs, low quantum efficiency, and insufficient utilization of solar energy. The system faces challenges such as difficult CO2 activation, insufficient local CO2 concentration, and weak intermediate stability in the CO2 reduction reaction.

• Molecular Study of Cadmium Sulfide and Graphene Oxide Interfaces for Photocatalytic Water Splitting Using Sunlight (2026) · Bulletin of the Karaganda University "Physics Series" · doi

  Future research should focus on experimental verification of the theoretical results. The study of other semiconductor photocatalysts and their interactions with graphene oxide is needed. Further research is required to understand the role of non-covalent interactions in regulating photocatalytic performance.
