A novel alkali metal sodium doped carbon nitride photocatalyst with a tunable band gap was prepared using dicyandiamide monomer and sodium hydrate as precursors. X-ray diffraction (XRD), N 2 adsorption, UV-vis spectroscopy, scanning electron microscopy (SEM), photoluminescence (PL) and X-ray photoelectron spectroscopy (XPS) were used to characterize the prepared catalysts. The CB and VB potentials of graphitic carbon nitride could be tuned by controlling the sodium concentration. In addition, sodium doping inhibited the crystal growth of graphitic carbon nitride, enhanced the surface area and increased the separation rate of photogenerated electrons and holes. The visible-light-driven Rhodamine B (RhB) photodegradation and mineralization performances were significantly improved after sodium doping.The possible influence mechanism of sodium concentration on the photocatalytic performance is proposed.

“…Jiang et al reported that two ions exchanged X zeolite, KCsÀ X, showed higher toluene conversion than the single ion exchanged X zeolites, KÀ X and CsÀ X. [40] The KCsÀ X zeolite showed higher utilization of methanol as compared with KÀ X and CsÀ X. However, the ratio of styrene to ethylbenzene decreased for KCsÀ X.…”

The literature on catalytic and mechanistic aspects of the sidechain alkenylation of toluene with methanol for the formation of styrene on solid base catalysts is reviewed. The development of catalysts and catalysis are described mostly on alkali ion exchange zeolite catalysts with fundamental chemistry related to the side-chain alkenylation. Mechanistic studies performed from various viewpoints are described. Methods to elucidate the reaction mechanisms are discussed based on the identification of the adsorbed species of the reactants, use of plausible intermediate compounds as reactant, characterization of surface properties to examine the correlation with reaction results, poisoning of the active sites by certain molecules, and theoretical calculations of the energy profile along with the reaction coordinate. These studies are discussed with critical assessments. The review addresses several challenges that prevent the side-chain alkenylation of toluene with methanol from industrialization which include decomposition of methanol to CO and H 2, and co-production of ethylbenzene. The paper covers mostly literature published during the period from 2000 to early 2021.
