“…The smaller arc and smaller R ct values indicate the smaller the charge transfer resistance between the electrode and electrolyte. 47,48 The wetter Cu 2 O/PDA/P25 electrode has a significantly lower surface charge transfer resistance. These charge dynamics results well match with the results of PEC performance.…”

“…In this regard, Wang and colleagues calculated the work function (Φ) using DFT in which the group computed electronic properties with geometric optimization via the Dmol code of Materials Studio (MS) software using DFT. The generalized gradient approximation (GGA) and Perdew–Burke–Ernzerhof (PBE) method is employed to compute the exchange-correlation (electrons), and Vienna Ab Initio Simulation Package (VASP) is utilized to calculate the work function (Φ) . In another work, Lia et al validate the S-scheme charge transfer mechanism of heterojunction photocatalyst (CdS/K 2 Ta 2 O 6 ) through DFT study using the GGA + PBE method, implemented in the VASP software .…”

In recent years, S-scheme oriented photocatalytic systems have shown tremendous potential and possibilities toward efficient conversion of solar energy to clear and sustainable chemical fuel owing to superior exciton separation and strong redox ability. This minireview summarizes the background history of the S-scheme mechanism along with a brief discussion of the type of band alignment and the journey from Z-scheme type to Sscheme systems. The review also elaborates the detailed operational mechanism and beneficial features of the S-scheme photocatalyst, including construction tactics, necessary conditions, band bending, and built-in electric field along with charge transfer dynamics. More importantly, we have described thoroughly the frequently used characterization techniques that demonstrate the interfacial charge transfer mechanism through S-scheme systems (XPS, in situ XPS, KPFM, and TRPL analysis) referring to the relevant reported literature with a brief computational interpretation. Additionally, the review highlights recent studies on the H 2 O 2 evolution reaction with particular emphasis on S-scheme-oriented systems. The conclusion and future prospective section focuses on associated challenges and insightful newly reported information for the research community to fully understand the chemistry of S-scheme-based charge flow and design, promising systems for achieving benchmark efficiency in the clean energy generation sector.

Rapid industrialization throughout the 20th and 21st centuries has led to the excessive consumption of fossil fuels to satisfy global energy demands. The dominant use of these fuel sources is the main cause of the ever-increasing environmental issues that greatly threaten humanity. Therefore, the development of renewable energy sources is fundamental to solving environmental issues. Solar energy has received widespread attention over the past decades as a green and sustainable energy source. Solar radiation-induced photocatalytic processes on the surface of semiconductor materials are able to convert solar energy into other energy sources for storage and further applications. However, the preparation of highly efficient and stable photocatalysts remains challenging. Recently, a new step-scheme (S-scheme) carrier migration mechanism was reported that solves the drawbacks of carrier migration in conventional heterojunction photocatalysts. The S-scheme heterojunction not only effectively solves the carrier migration problem and achieves fast separation but also preserves the powerful redox abilities and improves the catalytic performance of the photocatalytic system. To date, various S-scheme heterojunctions have been developed and employed to convert solar energy into useful chemical fuels to decrease the reliance on fossil fuels. Furthermore, these systems can also be used to degrade pollutants and reduce the harmful impact on the environment associated with the consumption of fossil fuels, including H2 evolution, pollutant degradation, and the reduction of CO2. H2O2 has been used as an effective, multipurpose, and green oxidizing agent in many applications including pollutant purification, medical disinfection, and chemical synthesis. It has also been used as a high-density energy carrier for fuel cells, with only water and oxygen produced as by-products. Photocatalytic technology provides a low-cost, environmentally friendly, and safe way to produce H2O2, requiring only solar energy, H2O, and O2 gas as raw materials. This paper reviews new S-scheme heterojunction designs for photocatalytic H2O2 production, including g-C3N4-, sulfide-, TiO2-, and ZnO-based S-scheme heterojunctions. The main principles of photocatalytic H2O2 production and the formation mechanism of the S-scheme heterojunction are also discussed. In addition, effective advanced characterization methods for S-scheme heterojunctions have been analyzed. Finally, the challenges that need to be addressed and the direction of future research are identified to provide new methods for the development of high-performance photocatalysts for H2O2 production.
