The manuscript discusses non-standard scientific and technological solutions for environmental monitoring, neutralization and subsequent deep processing of industrial and municipal waste. The manuscript is divided into three major sections devoted to monitoring, detoxification and processing of environmental pollutants. The following non-standard technological solutions for environmental monitoring are considered: Laser express chemical analysis; Laser remote sensing; Chemoresistive gas sensors for monitoring atmospheric conditions; Multi-beam optical analyzer for detection of microorganisms and organic pollutants. For neutralization of environmental pollutants, the following are considered: Modern catalysts for air purification from nitrogen and sulfur oxides; Adsorbents for carbon dioxide absorption; Advanced oxidation processes for purification of airport stormwater runoff; Advanced low-temperature plasma technologies; Catalysts for combustion of sewage sludge from municipal treatment facilities; Modern composite multifunctional polymer materials. Among technological solutions for deep processing of industrial and municipal waste, the following are considered: Nickel pincer complexes as electrocatalysts for molecular hydrogen evolution; Hydrogen sulfide-methane reforming for molecular hydrogen production; Technology of catalytic conversion of lignin-containing waste into adsorbents and fuel; New bacterial consortia for sewage sludge processing.

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.
