The interest of the global scientific community in problems CO<sub>2</sub> utilization and returning to carbon cycle has markedly increased recent years. Among various transformation processes, photocatalytic reduction is one most promising. Currently, much attention paid photocatalysts based on graphitic nitride, since use g-C<sub>3</sub>N<sub>4</sub> makes it possible perform under visible or solar light irradiation. To increase efficiency, subjected modifications with popular promising approach being synthesis composite other semiconductors form heterostructures. Depending type semiconductor, transfer photogenerated charge carriers these systems can occur by mechanisms, which largely determine course process rates formation reaction products. This review addresses studies g-C<sub>3</sub>N<sub>4</sub>, emphasis placed mechanisms carrier distribution products reduction. <br>The bibliography includes 235 references.

Green and sustainable electrocatalytic conversion of nitrogen-containing compounds to ammonia are currently in high demand order replace the eco-unfriendly Haber-Bosch process. Model catalysts for nitrate reduction reaction were obtained by electrodeposition metal Co, Fe bimetallic Fe/Co nanoparticles from aqueous solutions onto a graphite substrate. The samples characterized following methods: SEM, XRD, XPS, UV-vis spectroscopy, cyclic (and linear) voltammetry, chronoamperometry electrochemical impedance spectroscopy. Besides, determination electrochemically active surface was also performed all electrocatalysts. best electrocatalyst sample containing Fe-nanoparticles on layer Co-nanoparticles, which showed Faradaic efficiency 58.2% (E=-0.785 V vs. RHE) at yield rate 14.6 μmol h-1 cm-2. An opinion expressed elucidation mechanism coordinated action electrocatalyst. This work can serve primarily as starting point future investigations reactions using model proposed type.

As oil and gas companies are one of the major greenhouse emitters, they face increasing responsibility to address climate challenges. This highlights necessity integrating decarbonization options into their operations meet global objectives. While progress in technologies for capturing, utilizing, storing CO2 (CCUS technologies) is often attributed companies, CCUS projects sector predominantly focus on carbon storage, namely injection enhanced recovery, which presents limited possibilities. Meanwhile, capture utilization (CCU) offer a promising avenue producing valuable products from CO2, potential that has been underexplored theory practice within sector. study analyzes development full CCU cycle by assessing economic viability such projects. It includes content analysis research materials deployment case modeling methanol Russia. The findings indicate estimated minimum price CO2-based achieve project payback USD 1128 per ton, compared approximately 400 ton traditional methanol. gap underscores need foster low-carbon technologies, markets, measures support these In domain projects, cost-reduction could be more applicable, while regulatory measures, as taxes, currently have impact

The development of atom-economical and efficient processes for obtaining a variety chemical products using CO<sub>2</sub> as C<sub>1</sub>-synthon plays an increasingly important role in modern scientific technological research. Due to the inertness CO2 many extremely attractive routes valuable turn out be impossible implement, particularly thermodynamic reasons, leaving one only dreaming about them something unattainable. This review demonstrates how catalytic coupling ethylene into acrylic acid, once considered "dream reaction" has not become reality, but also evolved category processes. key stages long-term this unique reaction from discovery metal activation stoichiometric preparation metallalactones synthesis metal-catalysts (Ni, Pd, Ru, Rh) showcase ingenuity skill researchers well example consistent field chemistry. We believe that remarkably successful will inspire scientists tackle any "impossible" problems.<br> bibliography includes 117 references.

In this Viewpoint Article we explore three critical “atomic‐molecular” challenges: Earth's limited atomic its oxidative nature, very rich chemistry. Addressing these requires transformation in how produce consume, emphasizing sustainable practices aligned with United Nations’ 17 goals. The advancement science technology has extended human life expectancy improved quality life. However, to ensure future, must move towards less chemical processes, incorporate CH 4 −CO 2 redox chemistry into circular economy, transition linear, fossil fuel‐dependent economy bioeconomy.
