Special Issue Information

Dear Colleagues,

The global challenges of environmental pollution and energy scarcity have led to significant attention toward innovative solutions. This Special Issue aims to address these issues by focusing on the intersection of two critical fields: photocatalysis technology and green chemistry. Photocatalysis, with its ability to convert solar energy into valuable fuels and chemicals while mitigating organic pollutants, stands out as a promising approach to combat global energy shortages and environmental pollution. This call for papers is extended to researchers worldwide who are actively contributing to the field of photocatalysis, particularly those working on advanced photocatalytic materials. These materials play a pivotal role in various applications such as water splitting, CO2 reduction, ammonia synthesis, H2O2 synthesis, pollutant degradation, and organic synthesis.

Green chemistry, as an overarching philosophy, complements this initiative by emphasizing the design of chemical products and processes that prioritize sustainability. It not only prevents pollution at the molecular level but also spans across all facets of a chemical product's life cycle, from design to disposal. By applying innovative scientific solutions, green chemistry results in a source reduction, effectively preventing the generation of pollution. Moreover, it significantly reduces the negative impacts of chemical products and processes on both human health and the environment, emphasizing the intrinsic safety of the materials used in photocatalytic applications.

Photocatalysis performs excellently when degrading organic pollutants, but the photocatalytic degradation rate is not high for most photocatalysts due to their narrow sunlight adsorption range and high recombination rate of electron hole pairs. Herein, we use V2C-MXene with a wide sunlight adsorption range to couple ZnO porous nanosheets and form ZnO/MXene hybrids using a facile electrostatic self-assembly method. The ZnO/MXene hybrids acquired demonstrated improved photochemical efficiency in breaking down methylene blue (MB) when contrasted with porous ZnO nanosheets. The degradation rate of MB reached 99.8% under UV irradiation for 120 min after the ZnO/MXene hybrid formation, while 38.6% was attained by the ZnO porous nanosheets. Moreover, photodegradation rate constants (k) were calculated as 3.05 × 10−3 and 5.42 × 10−2 min−1 for ZnO porous nanosheets and ZnO/MXene hybrids, respectively, indicating that the photodegradation performance was enhanced by 17.8 times after the modification of V2C. This was probably because the modification of V2C can increase the specific surface area to provide more sites for MB adsorption, widen the sunlight adsorption range to produce good photothermal effect, and facilitate the transfer of photogenerated carriers in ZnO to promote the reaction of more photogenerated carriers with MB. Hence, this work offers a simple approach to creating effective photocatalysts for breaking down organic contaminants. Full article
