“…introduced an egative surface charge over the entire pH range,promoted interfacial electron transfer to dioxygen, and suppressed the decomposition of in situ generated H 2 O 2 . Consequently,the rate of H 2 O 2 formation on K-P-O-doped g-C 3 N 4 was markedly enhanced in an O 2 -saturated suspension compared to that of pure g-C 3 N 4 .I na nother related study, Zhang et al [67] reported the preparation of g-C 3 N 4 nanorods doped with halogen atoms (Br or Cl) by ahydrothermal posttreatment with as aturated NH 4 Br or NH 4 Cl solution. The introduction of heteroatoms into the p-conjugated g-C 3 N 4 positively shifted the boundary of the visible-light absorption and effectively accelerated the transfer rate of the charge carriers.T he results indicated that the Br-doped g-C 3 N 4 photocatalyst gave the highest photocatalytic H 2 O 2 production of 1.99 mmol L À1 ,which was over 2-and 1.25-fold higher than that of the g-C 3 N 4 and Cl-doped g-C 3 N 4 photocatalysts, respectively.M ore recently,K im et al [68] studied the codoping of metal (K) and nonmetal ions (P and F) into the g-C 3 N 4 framework.…”

Hydrogen peroxide (H2O2) has received increasing attention because it is not only a mild and environmentally friendly oxidant for organic synthesis and environmental remediation but also a promising new liquid fuel. The production of H2O2 by photocatalysis is a sustainable process, since it uses water and oxygen as the source materials and solar light as the energy. Encouraging processes have been developed in the last decade for the photocatalytic production of H2O2. In this Review we summarize research progress in the development of processes for the photocatalytic production of H2O2. After a brief introduction emphasizing the superiorities of the photocatalytic generation of H2O2, the basic principles of establishing an efficient photocatalytic system for generating H2O2 are discussed, highlighting the advanced photocatalysts used. This Review is concluded by a brief summary and outlook for future advances in this emerging research field.

“…[ 41 ] As a result, the fluorine doping of PCN altered the electronic band structures and improved photocatalytic activities for both hydrogen production from triethanolamine solution and benzene oxidization under visible‐light irradiation. Similarly, NH 4 Cl and NH 4 Br were also introduced during PCN formation from thermal condensation of melamine [38b,58] . Instead of forming a covalent bond with C, the Cl and Br elements existed in PCN as ions (Cl − , Br − ) that possibly bound with protonated amino groups (NH x + ).…”

Polymeric carbon nitride (PCN) is a metal‐free semiconductor that has received extensive research attention due to its unique advantages such as low cost, high stability, and visible‐light response. However, pristine PCN is not an ideal photocatalyst because of fast electron–hole recombination and its inert surface for molecular adsorption. Nevertheless, benefiting from the N‐linked tri‐s‐triazine structure, PCN can be readily functionalized through chemical modifications. As such, researchers have made enormous efforts to develop various strategies for modifying PCN to achieve enhanced photocatalytic activities. Herein, recent advances in PCN functionalizations with different atomic or molecular units, including metal and nonmetal elements, small functional groups, organic functional fragments, and metal complex motifs, are summarized. Moreover, the effect of different PCN functionalization strategies on the molecular structure, optical properties, electronic behaviors, and photocatalytic activities particularly for water splitting and CO2 reduction is discussed. In the end, the remaining challenges in the structural modification of PCN and future opportunities of functional PCN‐based photocatalysts for efficient solar fuel production are elaborated on.

Wasserstoffperoxid (H2O2) steht verstärkt im Fokus der Forschung, da es nicht nur ein mildes und umweltschonendes Oxidationsmittel für die organische Synthese und Umweltsanierung ist, sondern auch ein aussichtsreicher flüssiger Brennstoff. Die Herstellung von H2O2 mittels Photokatalyse ist ein nachhaltiger Prozess, da dabei Wasser und Sauerstoff als Ausgangsmaterialien und Sonnenlicht als Energiequelle genutzt werden. In den letzten zehn Jahren wurden ermutigende Fortschritte in der Entwicklung von Prozessen zur photokatalytischen H2O2‐Produktion erzielt. In diesem Aufsatz bieten wir eine umfassende Zusammenfassung der Fortschritte auf dem Gebiet der photokatalytischen Produktion von H2O2. Nach einer kurzen Einleitung, in der die Vorteile der photokatalytischen H2O2‐Synthese herausgestellt werden, diskutieren wir die grundlegenden Prinzipien der Entwicklung effizienter photokatalytischer Systeme zur Produktion von H2O2 und stellen moderne Photokatalysatoren vor. Wir schließen den Aufsatz mit einer kurzen Zusammenfassung und einem Ausblick über die Fortschritte in diesem wachsenden Forschungsgebiet ab.
