- A Floatable S‐Scheme S‐pCN/BiVO 4 /HPU–PGG System Forming the Three‐Phase Interface to Promote High‐Efficiency H 2 O 2 Production Zijing Chuai Jingkun Wang Naik Muhammad Xiujie Tan Wenping Xu Qiqiao Zhou Jiahua Duan Jujie Luo Chunyan Yu Tianbao Li Bingshe Xu ChemSusChem Achieving high solar‐to‐chemical conversion (SCC) efficiency is imperative for the practical application of semiconductors photocatalytic H 2 O 2 production. However, this objective remains significantly challenging due to limitations inherent in conventional systems, including inefficient light harvesting, rapid charge recombination, and mass transfer constraints. To address these bottlenecks, a synergistic “material‐system” design is validated. At the material level, ultraviolet‐visible, X‐ray photoelectron spectroscopy, and time‐resolved photoluminescence analyses confirm that the S‐pCN/BiVO 4 S‐scheme heterojunction significantly broadens visible light absorption and facilitates directed charge separation. At the system level, contact angle and kinetic analyses demonstrate that anchoring the catalyst onto a hydrophilic polyurethane–poly (propylene glycol) (HPU–PGG) hydrogel creates a floatable platform with a three‐phase interface, enabling direct atmospheric oxygen utilization and superior mass transfer. Furthermore, the system's physical architecture effectively isolates the photocatalyst from the H 2 O 2 product, suppressing undesirable decomposition. Consequently, the S‐pCN/BiVO 4 /HPU–PGG system achieves a high H 2 O 2 yield of 488μmol/L/h under visible light irradiation. This synergistic design achieves an SCC efficiency of 0.85%, which is eight times higher than that of natural photosynthesis. 10.1002/cssc.70737 http://onlinelibrary.wiley.com/termsAndConditions#vor
