Summary: In this study, a palladium-single-atom-coordinated cyano-group-rich g-C3N4 (Pd/D-N-UCN) was synthesized to improve the photocatalytic hydrogen evolution activity. The formation mechanism of Pd single atoms on g-C3N4 nanosheets and the coordination bonding of cyano groups with Pd atoms were proposed. The synthesized 0.16%Pd/D-N-UCN exhibited enhanced photocatalytic hydrogen production activity compared to electrostatically stabilized Pd single atoms.

Summary: Photocatalytic nitrogen fixation is a promising approach for ammonia synthesis, but the preparation of efficient catalysts and the understanding of reaction pathway and mechanism remain challenging. In this study, single-atom Fe-porous g-C3N4 (FPx) samples were prepared via a one-step annealing technique, and FPx exhibited a porous structure and single-atom Fe, leading to enhanced photocatalytic activity due to the exposure of more active centers and the change of adsorption mode of N2. FPx achieved a remarkable photocatalytic activity of 62.42 μmol h-1 g-1 without any sacrificial agent or cocatalyst, which is over five times higher than that of bulk g-C3N4. This work provides new insights into photocatalytic nitrogen fixation and offers a strategy for efficient N2 photoreduction by constructing single-atom photocatalysts.

Summary: Controlling the structure of semiconductors is crucial for tailoring their physicochemical and photoelectronic properties. Graphitic carbon nitride has shown potential in photocatalysis, but its photocatalytic activity is limited by the rapid recombination of charge carriers. In this study, we demonstrate that introducing potassium doping and nitrogen defects into graphitic carbon nitride can enhance visible light absorption, improve charge separation, and significantly enhance the photocatalytic behavior for water splitting.

Summary: By constructing 1D strip-like carbon nitride from carbon-doping, this study addresses the issues of high carrier recombination rate and low charge transfer efficiency, improving the hydrogen evolution rate significantly. The effective pi delocalization and porous structure of the carbon-doped 1D carbon nitride play a key role in accelerating charges and mass transfer, leading to a much higher hydrogen evolution rate compared to polymeric carbon nitride under visible light irradiation.

Summary: In this study, researchers propose a versatile strategy that utilizes carbon vacancies to regulate the electronic configuration of antimony (Sb) atoms on carbon nitrides (C3N4), significantly enhancing the photocatalytic production of H2O2. The H2O2 evolution rate of Sb single-atom on carbon vacancy-rich C3N4 is 10.9 times higher than C3N4 alone. The strong electronic interaction between Sb atoms and carbon vacancy-rich C3N4 is capable of maintaining the electron-rich state of Sb atoms, facilitating efficient electron transfer, and enhancing the formation of *OOH intermediates.

Summary: In this study, a challenging task of depolymerizing lignin into aromatic monomers with high yield and selectivity via photocatalysis was achieved. Reduced graphene oxide (rGO) nanosheets were introduced as solid electronic mediators to synthesize g-C3N4/rGO/CdS ternary nanocomposites. The photocatalysts efficiently broke the C-C bond of lignin under simulated sunlight conditions. Characterization results showed that the loading of CdS enhanced light absorption range and accelerated the transfer of charge carriers, while the introduction of rGO inhibited recombination of electron-hole pairs. Using the β-O-4 model substrate, a 95% conversion rate was achieved with higher yields of benzaldehyde and phenyl formate compared to pure g-C3N4. Our research highlights the importance of energy band structure engineering and electronic mediator design in developing efficient photocatalysts for breaking C-C bonds of lignin.

Two outstanding T-1-weighted contrast agents (CAs), Gd-PAA12 and Gd-PASP11 OGMCs, are synthesized with high r(1) values and low r(2)/r(1) ratios. The ferromagnetism of OGMCs leads to low r(2), making them preferred for T-1 MRI, and Gd3+ is not released, ensuring biosafety.
