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.

Photocatalytic reduction of carbon dioxide is a very effective strategy to address the energy crisis and greenhouse effect. TiO2 is a widely used semiconductor photocatalyst, which has excellent catalytic activity, excellent chemical stability and low toxicity. Nevertheless, TiO2 still has some inherent limitations, such as: wide band gap, high carrier recombination rate, and low adsorption activation ability for carbon dioxide. These drawbacks severely restrict its further application in the photocatalytic reduction of CO2. In this study, cotton-like blue C/TiO2 NTs are successfully synthesized through the in situ growth of TiO2 nanotubes on the MIL-125(Ti)-derived C/TiO2 precursor. The experimental results revealed that the CO production rate of the cotton-like blue C/TiO2 NTs was 1.84 times that of C/TiO2 and 3.78 times that of TiO2 nanotubes. These results clearly demonstrate that the cotton-like blue C/TiO2 NTs exhibit a broad spectral response, a large specific surface area, and an abundance of oxygen vacancies. This research provides new insights into the design of titanium dioxide-based photocatalytic materials and opens up a promising avenue for enhancing the performance of titanium dioxide in the photocatalytic reduction of carbon dioxide.
