A new type of elastomeric composite containing natural rubber (NR) and graphitic carbon nitride (g-C 3 N 4 ) has been successfully prepared with the reinforced property. The reinforcing effect of g-C 3 N 4 in NR composites was examined by cure, mechanical, morphological, and swelling studies. Besides, epoxidized NR with 50-mol % epoxy level (ENR-50) was used as a compatibilizer to enhance the hydrophilic g-C 3 N 4 filler capacity for hydrophobic NR composites. At the same filler load level, the mechanical properties of NR/g-C 3 N 4 composites, such as tensile strength and tensile modulus, were consistently increased with increased ENR-50 content. To note, the ENR compatibilized composites have shown better-reinforced performance, which has been attributed to the hydrogen bonding interactions between the uncondensed amine groups in g-C 3 N 4 and the polar groups in ENR. We believe that these newly prepared NR composites based on g-C 3 N 4 as nonblack filler and ENR-50 as compatibilizer can find potential applications in modern day rubber research.

“…However, g‐C 3 N 4 has suffered from the charge recombination issue, which limits the photocatalytic performance of the material. Methods such as structural engineering, heteroatoms doping, introducing cocatalysts, and introducing nitrogen vacancies as defects have been studied to improve the photocatalytic performance of g‐C 3 N 4 . To date, the work by Dong et al on promoting nitrogen vacancy to g‐C 3 N 4 (V‐g‐C 3 N 4 ) demonstrates the highest rate of ammonia production ( r NH3 ) among other methods.…”

Ammonia (NH3) is one of the essential chemicals as a fertilizer and as a starting reagent for various chemicals with a production expectation of 200 million tonnes for 2018. With the development of renewable energy technologies such as hydrogen fuel cells, hydrogen also has emerged as an innovative clean energy source. Ammonia is a suitable hydrogen fuel carrier since a molecule of ammonia can carry up to three atoms of hydrogen. Recently, photochemical synthesis via nitrogen reduction has gained considerable attention as a sustainable method for the production of ammonia. The performance of the photoreduction of nitrogen lies in the developments of the photocatalysts and photoelectrocatalysts. Therefore, it is essential to understand the fundamentals of nitrogen reduction processes along with apprehending the challenges that limit the progress of catalysts. In this review, the basic understanding of photoreduction of nitrogen is highlighted, emphasizing on the challenges and effective methods to control defects, structures, and morphologies of materials for the catalyst development. The methods for ammonia detection and uncertainties in calculating the efficiency of the photochemical process are also addressed.

“…However, the band gap of TiO 2 is 3.2 eV, which limits the utilization efficiency of sunlight [29][30][31]. Graphitic carbon nitride (g-C 3 N 4 ), as a metal-free semiconductor with band gap of 2.7 eV and excellent chemical stability [32], has been widely investigated in photocatalytic hydrogen production with water [33], degradation of organic pollutants [34][35][36][37][38], oxidation of alcohols [39], reduction of oxygen [40], etc. Recently, graphitic carbon nitride quantum dots (CNQDs) with excellent biocompatibility and optical properties [41] which can improve solar energy harvesting, were synthesized by a lowtemperature solid-phase method [42].…”

Indoor toxic volatile organic compounds (VOCs) pollution is a serious threat to people’s health and toluene is a typical representative. In this study, we developed a composite photocatalyst of carbon nitride quantum dots (CNQDs) in situ-doped TiO2 inverse opal TiO2 IO for efficient degradation of toluene. The catalyst was fabricated using a sol-gel method with colloidal photonic crystals as the template. The as-prepared catalyst exhibited excellent photocatalytic performance for degradation of toluene. After 6 h of simulated sunlight irradiation, 93% of toluene can be converted into non-toxic products CO2 and H2O, while only 37% of toluene is degraded over commercial P25 in the same condition. This greatly enhanced photocatalytic activity results from two aspects: (i) the inverse opal structure enhances the light harvesting while providing adequate surface area for effective oxidation reactions; (ii) the incorporation of CNQDs in the framework of TiO2 increases visible light absorption and promotes the separation of photo-generated charges. Collectively, highly efficient photocatalytic degradation of toluene has been achieved. In addition, it can be expanded to efficient degradation of organic pollutants in liquid phase such as phenol and Rhodamine B. This study provides a green, energy saving solution for indoor toxic VOCs removal as well as for the treatment of organic wastewater.
