الوصف: The coupling of H 2 O and O 2 by solar energy is regarded as the Holy Grail reaction for a manufacturing route of H 2 O 2 ; however, its efficiency has suffered from low O 2 solubility in aqueous solution and difficult-to-inhibit side reactions. Herein, a liquid–solid–gas triphase system has been designed to directly utilize abundant atmospheric O 2 for H 2 O 2 photosynthesis, the most important of which is the superhydrophobic photocatalyst of amino-containing ligands combined with Pd, loaded on BiVO 4 (Pd/A/BiVO 4 ). This relatively separated catalyst and product system successfully avoids the decomposition of produced H 2 O 2 and contributes to the accumulation of a high-concentration H 2 O 2 solution. The enrichment of O 2 and the kinetics of carriers and reaction intermediates are tunable via the interaction between Pd and amino groups, which promotes the photosynthetic yield of H 2 O 2 to 805.9 μmol g –1 h –1 in pure water under visible illumination. During the reaction, O 2 is not only converted into H 2 O 2 as a reactant but also participates in the construction of Pd-O x sites as a dynamic catalyst. Also, the Pd-O x intermediate is identified as a catalytic and photoelectronic dual center. This research opens up an intriguing avenue for designing the H 2 O 2 photosynthesis system.
