Summary: A facile strategy for the fabrication of plasmonic titanium nitride/g-C3N4 with intimate contact was proposed to enhance the photocatalytic CO2 reduction. Under optimized conditions, the g-C3N4-2.8TiN showed the highest CO production rate of approximately 820 mu mol g-1 h-1 and apparent quantum yield of 3.5% at 400 nm, as well as 0.43% at 550 nm, which are among the highest reported values for g-C3N4-based materials. This work offers promising opportunities to fabricate low-cost plasmonic nanoparticle/semiconductor systems for solar energy applications.

Summary: A bio-surfactant assisted synthesis route has been used to decorate gold nanoparticles on g-C3N4 for the reduction of mono-nitrophenols under visible light irradiation. The biomolecules of the leaf extract and optimized reaction conditions played a crucial role in controlling the morphology and optoelectronic properties of the nanoparticles. The plasmonic hybrid photocatalyst, 3%wt AuNPs loaded on g-C(3)N(4), exhibited high photoreduction efficiency for nitrophenols, attributed to the synergy between the conduction band of g-C3N4 and the plasmonic band of AuNPs.

Summary: The excessive usage of fossil fuels results in a vast amount of CO2 exposure to the ecosystem, leading to global ecological imbalance. CO2, aside from being a pollutant, has the potential to be converted into useful carbonaceous products when exposed to light. In this study, researchers fabricated a 1:1 ratio of g-C3N4-Ce2S3 heterostructure through a solvothermal approach. The GCN/CeS heterostructure exhibited enhanced activity in selective CO2 conversion and showed effectiveness in degrading the herbicide Atrazine under visible light. LC-MS analysis revealed the degradation pathway and mechanism of Atrazine in the GCN/CeS heterostructure. The stability of the GCN/CeS heterostructure demonstrated its potential in photocatalytic processes.

Summary: A porous g-C3N4/Au composite catalyst was prepared by a composite strategy of three-dimensional morphology construction and plasmonic Au nanoparticle anchoring, which improved the photocatalytic carbon dioxide reduction reaction efficiency. The yields of CO, CH4, and C2H4 were significantly increased under UV-Visible light irradiation, and the yield of CO was greatly enhanced under visible light irradiation. The enhancement of photocatalytic efficiency can be attributed to the 3D porous structure, slow photon effect, LSPR effect, increased reactive sites, and enhanced CO2 adsorption.

Summary: Photocatalytic CO2 reduction can address both the energy crisis and environmental issues. However, designing photocatalysts with efficient carrier mobility remains a challenge. In this study, a microwave-assisted method was used to construct a Bi2MoO6/g-C3N4 (BMO/CN) heterostructure, enhancing the formation of two-dimensional (2D) structures. The 2D BMO/CN junction exhibited superior performance in photocatalytic CO2 reduction. The optimized BMO/CN-30% catalyst showed a CO and CH3OH production rate of 2.44 and 3.61 μmol·g(-1)·h(-1) respectively. The formation of HCO3- intermediate was observed by in-situ FT-IR, confirming the evolution of CH3OH. This study highlights a microwave-assisted approach for enhancing photoreduction of CO2.

Summary: We report an oxygen vacancy (V-o)-rich metallic MoO2-x nano-sea-urchin with partially occupied band, which exhibits super CO2 photoreduction performance under UV, visible and NIR light. The V-o-rich MoO2-x nano-sea-urchin shows significantly higher CH4 evolution rate compared to the V-o-poor MoO2-x, and can even reduce CO2 directly from the air. Experimental and theoretical results suggest that the oxygen vacancy in MoO2-x facilitates CO2 adsorption/activation and subsequent protonation of *CO towards the formation of CH4 due to the formation of a highly stable Mo-C-O-Mo intermediate.

Summary: Inspired by the lotus leaf effect, a hydrophobic graphitic carbon nitride (g-C3N4) photocatalyst modified by CF2 groups (CF2-TCN) is developed to enhance its aerophilicity in air. The CF2 groups create a hydrophobic surface, acting as a gas transport layer, and theoretical calculations support that the electronegativity of F atoms affects the electron cloud distribution and facilitates the adsorption and activation of CO2. Experimental characterizations show that CF2-TCN exhibits improved CO2 photoreduction performance compared to bulk g-C3N4.

Summary: The fabrication of Van der Waals (VDW) heterojunctions between 2D materials has attracted researchers' interest due to their compact interfaces, low energy barriers, and efficient electron mobility. However, weak VDW interactions and a VDW gap hinder carrier migration across layers. This study developed a novel ZnxCd1-xS/g-C3N4 catalyst, which regulates VDW heterojunctions through interface engineering. The constructed Cd-N bonds at the interface serve as an electron transport bridge, enabling efficient migration of photogenerated electron-hole pairs. As a result, Zn0.8Cd0.2S/g-C3N4 exhibits enhanced CO2 reduction performance, surpassing pure g-C3N4 without co-catalysts or sacrificial agents. This work provides insights into regulating Van der Waals heterojunctions and offers an efficient photocatalyst for green energy conversion.

Summary: Photocatalysis is a sustainable method for NOx elimination, but efficient and safe removal of NOx remains challenging. This study reports the synthesis of sulfur-doped g-C3N4 nanosheets (CNN-S) with improved light absorption and charge separation. The photocatalytic activity for NO removal increased from 17% (bulk g-C3N4) to 35% (CNN-S0) and reached a maximum of 53% with a sulfur content of 0.5. The enhanced performance is attributed to the increased surface area and effective charge transfer facilitated by the nanosheet structure and sulfur doping.

Summary: In recent years, photocatalysis using graphite carbon nitride (g-C3N4) as a photocatalyst has attracted increasing attention for energy scarcity and environmental treatment. However, there are still challenges in achieving desirable photocatalytic performance of g-C3N4. Functional group functionalization, as a common modification technique, can modulate the carrier dynamics and increase the number of active sites, offering new opportunities for structure-to-performance relationship of g-C3N4. A review of the recent development of functional group modification is urgently needed to better understand the molecular level structure-to-performance relationship and explore the future research direction.

Summary: In this study, Ni cocatalysts on a TiO2 composite photocatalyst with different graphene oxide (GO) contents were prepared using a hydrothermal method and characterized. It was found that the TiO2/GO/Ni nanosheet composites have a large specific surface area and can provide a large number of active sites for photocatalytic hydrogen production. GO can broaden the optical absorption range of TiO2 and absorb more visible light, stimulating the generation of more electron-hole pairs. Additionally, GO can collect electrons and promote the separation of electron-hole pairs. Ni, as a cocatalyst, can adsorb hydrogen ions and facilitate the migration of photogenerated electrons, thus ensuring high efficiency of the photocatalytic reaction.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
