The discovery of new carbon materials and the reactive activation of CaC are challenging subjects. In this study, a series of alkynyl carbon materials (ACMs) were synthesized by the interfacial mechanochemical reaction of CaC with four typical polyhalogenated hydrocarbons. Their properties and structures were characterized, and their electrochemical performances were examined. The reaction was rapid and efficient arising from the intense mechanical activation of CaC. The ACMs are micro-mesoporous materials with distinct layered structure, specific graphitization degree, and clear existence of sp-C. In addition, the ACMs exhibit high specific capacitance in the range of 57-133 F g and thus can be ideal candidates for active materials used in supercapacitors. The results may imply an alternative synthesis of carbon allotropes, as well as an efficient approach for the activation of CaC.

“…The photocatalyst PtO x -RGO-CN x was prepared as diagrammatized in Figure . First, g-C 3 N 4 was synthesized through a thermal polymerization method using urea as a precursor following a modified method reported previously. , Then, g-C 3 N 4 was hydrothermally treated in the aqueous solution of ammonia to obtain the deprotonated g-C 3 N 4 (CN x ) . An aqueous dispersion of 100 mg CN x was sonicated for 30 min, and a certain amount of graphene oxide (GO; 3, 5, and 10 wt %, respectively) was added to the suspension and stirred evenly.…”

Photocatalytic overall water splitting is considered as an ideal solution to the energy crisis by converting inexhaustible solar energy into hydrogen energy. However, the practical application of photocatalytic overall water splitting is hindered by the challenges including unfavorable four-electron/hole kinetics and H 2 /O 2 separation. Here, the binary composite of reduced graphene oxide and graphitic carbon nitride decorated by the double cocatalyst (Pt and PtO 2 ) is reported to achieve excellent photocatalytic water reforming performance for H 2 and H 2 O 2 production via the two-electron pathway. In addition, a unique structure with Pt and PtO 2 as active sites for reduction and oxidation, respectively, is further proposed. This unique structure promotes the separation of photogenerated carriers and holes, extends the light absorption, and thus significantly improves photocatalytic activity with the highest H 2 evolution rate of 5.7 μmol•h −1 . What's more, the addition of reduced graphene oxide can improve the photocatalytic stability of the catalyst by reinforcing the chemical connection between graphitic carbon nitride and PtO x (Pt, PtO 2 ). This work highlights the important role of using graphitic carbon nitride for heterogeneous catalysis and reveals the possibility of designing multiple components to realize an efficient photocatalytic water reforming.
