“…The conventional method utilized for converting methane into syngas is steam methane reforming (SMR). 11,[14][15][16][17][18][19] Almost all commercial processes for synthesizing higher-value products from methane begin with the SMR method, which produces hydrogen and carbon monoxide, which are utilized for the synthesis of other chemicals. 4,[20][21][22][23][24] However, the SMR process necessitates high temperature and pressure conditions, is energy-intensive, and generates substantial carbon emissions.…”

“…The electrocatalytic oxidation of methane is strongly influenced by potential, and the products of the same catalyst at different potentials can be different. 16,[126][127][128] Electrochemistry is dependent on potential, and in electrocatalytic methane oxidation, the electrolytic voltage is often selected as follows: Oh et al 104 analyzed the impact of potential on a ZrO 2 NT/Co 3 O 4 catalyst.

Conspectus The carbon balance has been disrupted by the widespread use of fossil fuels and subsequent excessive emissions of carbon dioxide (CO2), which has become an increasingly critical environmental challenge for human society. The production and use of renewable energy sources and/or chemicals have been proposed as important strategies to reduce emissions, of which the electrochemical CO2 (or CO) reduction reaction (CO2RR/CORR) in the aqueous systems represents a promising approach. Benefitted by the capacity of manufacturing high-value-added products (e.g., ethylene, ethanol, formic acid, etc.) with a net-zero carbon emission, copper-based CO2RR/CORR powered by sustainable electricity is regarded as a potential candidate for carbon neutrality. However, the diversity of selectivities in copper-based systems poses a great challenge to the research in this field and sets a great obstacle for future industrialization. To date, scientists have revealed that the electrocatalyst design and preparation play a significant role in achieving efficient and selective CO2-to-chemical (or CO-to-chemical) conversion. Although substantial efforts have been dedicated to the catalyst preparation and corresponding electrosynthesis of sustainable chemicals from CO2/CO so far, most of them are still derived from empirical or random searches, which are relatively inefficient and cost-intensive. Most of the mechanism studies have suggested that both intrinsic properties (such as electron states) and extrinsic environmental factors (such as surface energy) of a catalyst can significantly alter catalytic performance. Thus, these two topics are mainly discussed for copper-based catalyst developments in this Account. Here, we provided a concise and comprehensive introduction to the well-established strategies employed for the design of copper-based electrocatalysts for CO2RR/CORR. We used several examples from our research group, as well as representative studies of other research groups in this field during the recent five years, with the perspectives of tuning local electron states, regulating alloy phases, modifying interfacial coverages, and adjusting other interfacial microenvironments (e.g., molecule modification or surface energy). Finally, we employed the techno-economic assessment with a viewpoint on the future application of CO2/CO electroreduction in manufacturing sustainable chemicals. Our study indicates that when carbon price is taken into account, the electrocatalytic CO2-to-chemical conversion can be more market-competitive, and several potential value-added products including formate, methanol, ethylene, and ethanol can all make profits under optimal operating conditions. Moreover, a downstream module employing traditional chemical industrial processes (e.g., thermal polymerization, catalytic hydrolysis, or condensation process) will also make the whole electrolysis system profitable in the future. These design principles, combined with the recent advances in the development of efficient copper-based electrocatalysts,...

Airborne pollutants, such as nitrogen oxides (NOx), and waterborne contaminants, including heavy metals, dyes, and other pollutants, pose substantial environmental threats and jeopardize human health. Additionally, certain limitations have hindered the widespread application of some batteries, primarily attributed to elevated operating temperatures and the decreasing use of fossil fuels. In response to these challenges, cerium dioxide (CeO2) nanoparticles have garnered considerable attention due to their unique and advantageous physical and chemical properties. Furthermore, the incorporation of CeO2 into various coating materials has demonstrated the potential to significantly enhance their performance. In the realm of biotechnology, research into CeO2 nanoparticles continues to expand, encompassing a range of applications such as the scavenging of reactive oxygen species (ROS) in biological systems, the development of anti‐inflammatory agents, and cancer research. Nevertheless, in these diverse applications, CeO2 still exhibits certain limitations that hinder the achievement of desired outcomes. The modification of CeO2 nanoparticles presents a promising avenue to address these limitations, thereby improving their overall efficacy. As such, this review aims to comprehensively compare and summarize various methods for the modification of CeO2 nanoparticles, elucidate their practical applications, and provide insights into the potential challenges and future prospects in this field.This article is protected by copyright.
