“…In addition, the connection between the suitable specific surface area and the variables affects the sample’s photocatalytic performance. We calculated the pore size and pore distribution of each sample using the Barrett–Joyner–Halenda technique and the Halsey equation, as shown in Table S1 (Supporting Information) [ 32 , 33 , 34 ]. From the nitrogen adsorption data of the six catalyst samples, when compared to CdS, the specific surface area of CdS-TiO 2 has increased in comparison to commercial P25 and CdS-C 60 , but the rate of the change in the pore size is much greater than the change in the specific surface area.…”

The inherent properties of TiO2, including a wide band gap and restricted spectral response range, hinder its commercial application and its ability to harness only 2–3% of solar energy. To address these challenges and unlock TiO2’s full potential in photocatalysis, C60- and CdS-co-modified nano-titanium dioxide has been adopted in this work to reduce the band gap, extend the absorption wavelength, and control photogenerated carrier recombination, thereby enhancing TiO2’s light-energy-harnessing capabilities and hydrogen evolution capacity. Using the sol-gel method, we successfully synthesized CdS-C60/TiO2 composite nanomaterials, harnessing the unique strengths of CdS and C60. The results showed a remarkable average yield of 34.025 μmol/h for TiO2 co-modified with CdS and C60, representing a substantial 17-fold increase compared to pure CdS. Simultaneously, the average hydrogen generation of C60-modified CdS surged to 5.648 μmol/h, a notable two-fold improvement over pure CdS. This work opens up a new avenue for the substantial improvement of both the photocatalytic degradation efficiency and hydrogen evolution capacity, offering promise of a brighter future in photocatalysis research.

In recent times, mesoporous silica sieves gathered considerable attention from a fundamental as well as an applied perspective. Particularly, MCM‐41 has become increasingly popular among researchers because of its chemical flexibility and application in various fields. In addition, MCM‐41‐based materials are currently being extensively studied for their utility as substrates, adsorbents, catalysts, molecular hosts, and ion exchangers. This review article provides a thoughtful analysis of the developments in these areas, particularly emphasizing the recent advance in the functionalization of MCM‐41 via metal complex and their catalytic applications in a variety of reactions such as coupling reactions and oxidation reactions. This review explores the catalytic properties that led to such widespread use, and why there is now an increasing drive to synthesize such a catalytic system.
