Mechanistic study of the competition between carbon dioxide reduction and hydrogen evolution reaction and selectivity tuning loading single-atom catalysts on graphitic carbon nitride.

In the context of catalytic CO reduction (CORR), the interference of the inherent hydrogen evolution reaction (HER) and the possible selectivity towards CO have posed a significant challenge to the generation of formic acid. To address this hurdle, in this work, we have investigated the impact of different single-atom metal catalysts on tuning selectivity by employing density functional theory (DFT) calculations to scrutinize the reaction pathways. Single-atom catalysts supported on carbon-based systems have proven to be pivotal in altering both the activity and selectivity of the CORR.

Additive Manufacturing: A Paradigm Shift in Revolutionizing Catalysis with 3D Printed Photocatalysts and Electrocatalysts Toward Environmental Sustainability.

Semiconductor-based materials utilized in photocatalysts and electrocatalysts present a sophisticated solution for efficient solar energy utilization and bias control, a field extensively explored for its potential in sustainable energy and environmental management. Recently, 3D printing has emerged as a transformative technology, offering rapid, cost-efficient, and highly customizable approaches to designing photocatalysts and electrocatalysts with precise structural control and tailored substrates. The adaptability and precision of printing facilitate seamless integration, loading, and blending of diverse photo(electro)catalytic materials during the printing process, significantly reducing material loss compared to traditional methods.

Isotype heterojunction: tuning the heptazine/triazine phase of crystalline nitrogen-rich CN towards multifunctional photocatalytic applications.

Photocatalytic technology has been well studied as a means to achieve sustainable energy generation through water splitting or chemical synthesis. Recently, a low C/N atomic ratio carbon nitride allotrope, CN, has been found to be highly prospective due to its excellent electronic properties and ample N-active sites compared to g-CN. Tangentially, crystalline g-CN has also been a prospective candidate due to its improved electron transport and extended π-conjugated system.

A Prospective Life Cycle Assessment of Electrochemical CO Reduction to Selective Formic Acid and Ethylene.

Converting CO into valuable C -C chemicals through electrochemical CO reduction (ECR) has potential to remedy the ever-increasing climate problems owing to the intensification of industrial activity. In this work, cradle-to-gate life cycle assessment (LCA) was performed to quantify the environmental impacts of formic acid (FA) and ethylene production through ECR benchmarked with the conventional processes. At the midpoint level, global warming potential (GWP) effects of FA and ethylene production through ECR recorded 5.

The environmental impacts study containing the rGO production process, the ODS process, the comparison of different oxidants and solvents was developed. This study was performed by using ReCiPe 2016 V1.

Point-Defect Engineering: Leveraging Imperfections in Graphitic Carbon Nitride (g-C N ) Photocatalysts toward Artificial Photosynthesis.

Graphitic carbon nitride (g-C N ) is a kind of ideal metal-free photocatalysts for artificial photosynthesis. At present, pristine g-C N suffers from small specific surface area, poor light absorption at longer wavelengths, low charge migration rate, and a high recombination rate of photogenerated electron-hole pairs, which significantly limit its performance. Among a myriad of modification strategies, point-defect engineering, namely tunable vacancies and dopant introduction, is capable of harnessing the superb structural, textural, optical, and electronic properties of g-C N to acquire an ameliorated photocatalytic activity.
