“…Developing scalable synthesis methods for g-C 3 N 4 electrodes will facilitate their large-scale production. Innovative approaches like solvothermal, aerosol-assisted, or direct carbonization of nitrogen-containing precursors (Wang et al, 2020) can be explored (Villalobos et al, 2020). These techniques can promote efficient mass production of g-C 3 N 4 electrodes, making them more commercially viable (Ramar and Wang, 2022).…”

Graphitic carbon nitride (g-C3N4) has emerged as a promising material for various applications, particularly in the field of energy storage systems. Among these systems, lithium-ion batteries (LIBs) have become the cornerstone of portable electronics and are increasingly being adopted for electric vehicles and renewable energy storage. However, the search for alternative electrode materials that can overcome the limitations of traditional graphite anodes and transition metal oxide cathodes remains a significant challenge. In recent years, g-C3N4 has attracted considerable attention due to its unique physicochemical properties, such as high electrochemical stability, tunable bandgap, large specific surface area, and excellent thermal and chemical stability. Also, the low cost, abundance, and environmental sustainability of g-C3N4 contribute to its suitability for next-generation LIBs. However, the successful utilization of g-C3N4 as an electrode material is hindered by several challenges. This paper aims to explore the challenges and future perspectives of utilizing g-C3N4 as a potential electrode material for LIBs, highlighting the potential benefits and drawbacks of integrating this material into the battery system.

In this work, the use of graphite-like carbon nitride (g-C3N4) with improved texture characteristics for the synthesis of supported palladium catalysts of dehydrogenation of nitrogen-containing heterocycles was studied. This process is key to the creation of liquid organic carrier technology (LOHC) using N-heterocycles as reversibly hydrogenated/dehydrogenated substrates. For the preparation of graphite-like carbon nitride supports with advanced textural characteristics, well-established technology of the melamine cyanurate complex carbonization and standard techniques of adsorption precipitation together with wet impregnation were used for the synthesis of Pd-containing systems. The activity of the synthesized catalysts was studied in decahydroquinoline dehydrogenation. The high weight content of extractable hydrogen (7.2 wt%) and the high extraction rate, respectively, make it possible to consider these substances as the most promising N-heterocyclic compounds for this technology. It was shown that an increase in the specific surface area of g-C3N4 allows for achieving a slightly lower but comparable fineness of palladium particles for the 1 wt% Pd/MCA-500 sample, compared to the standard 1 wt% Pd/C. In this case, the catalytic activity of 1 wt% Pd/MCA-500 in the dehydrogenation of both substrates exceeded the analogous parameter for catalysts supported by nitrogen-free supports. This regularity is presumably associated with the electron-donor effect of surface nitrogen, which favorably affects the dehydrogenation rate as well as the stability of catalytic systems.

“…Photocatalytic decomposition of organic substances occurs on the surface of a photocatalyst [11][12][13][14]. It is known that an increase in the specific surface increases the photocatalytic activity of coatings [15,16]. Therefore, the specific surface is an important parameter affecting the efficiency of photocatalysts.…”

The photocatalytic approach is known to be one of the most promising processes for the tertiary treatment of polluted water. The paper presents studies of Zn2SnO4 (ZTO) coatings synthesized by spray pyrolysis of Zn and Sn salt solution with the addition of dispersed Ta2O5 powder. The structural, morphological and optical properties of the coatings were investigated. Despite the simplicity and availability, the spray pyrolysis method provides homogeneous coatings. Introducing 0.001 mol/L of Ta2O5 into the initial salt solution was found to contribute to a significant change in the surface morphology of the synthesized coatings. The effect of the doped Ta2O5 phase on the photocatalytic activity of ZTO for the degradation of methylene blue (MB) has been investigated. An improvement of up to 90% in the degradation of MB has been observed for the Zn2SnO4/Ta 2O5 system after five hours of UV irradiation.
