“…Additionally, Campbell et al studied the FT performance of Co‐Rh/Nb 2 O 5 under 100 kPa, but the CO conversion is not attractive . Similarly, Co‐Ni‐Cs/La 2 O 3 catalyst exhibits low FT activity and C 5+ selectivity under low pressure . Accordingly, Co‐Re/Al 2 O 3 shows excellent seletivity to diesel fuels via FT synthesis and also attractive catalytic activity under investigated conditions.…”

This work deals with the improvement of diesel (C10‐C20) production of Fischer‐Tropsch (FT) synthesis at low pressure over Co‐Re/Al2O3 since high catalytic activity and great potential in producing C10‐C20 hydrocarbons were observed under conventional conditions. To improve the catalytic performance, CO conversion and hydrocarbon selectivity were investigated against pressure, syngas H2/CO ratio, gas flow rate, and temperature. 93.7 % of CO conversion was achieved as well as 62.3 % diesel selectivity over Co‐Re/Al2O3 catalyst even after working for 15 days, which was far higher than the maximum value of the Anderson‐Schulz‐Flory (ASF) distribution and the results in literature reports. It is suggested that Re plays an important role in enhancing dissociation of hydrogen as well as the formation of CH, CH2, and CH3 species to convert CO.

“…Syngas has been commonly used in production of methanol, olefin, crude oil and wax by Fischer-Tropsch synthesis [15][16][17]. Production of syngas from different of both nonrenewable and renewable sources such as methane [1,[18][19][20], coal, glycerol [21,22], methanol and biogas [23] is being widely researched.…”

“…In fact, the capability of CO 2 RR to store the intermittent renewable energy in the form of chemical fuels also helps address the storage issue that is limiting the transition to renewable resources . Moreover, there is a commercial drive for the adoption of this technology as the value‐added fuel and chemicals generated from CO 2 RR can be put into further usage, with potential applications for electricity production, transportation fuels, or chemical feedstocks . It is therefore possible to recuperate the costs of CO 2 RR through the use or sale of the converted products, potentially promoting the viability of this technology from a commercial perspective.…”

Renewable‐electricity‐powered electrocatalytic CO2 reduction reactions (CO2RR) have been identified as an emerging technology to address the issue of rising CO2 emissions in the atmosphere. While the CO2RR has been demonstrated to be technically feasible, further improvements in catalyst performance through active sites engineering are a prerequisite to accelerate its commercial feasibility for utilization in large CO2‐emitting industrial sources. Over the years, the improved understanding of the interaction of CO2 with the active sites has allowed superior catalyst design and subsequent attainment of prominent CO2RR activity in literature. This review tracks the evolution of the understanding of CO2RR active sites on different electrocatalysts such as metals, metal‐oxides, single atoms, metal‐carbon, and subsequently metal‐free carbon‐based catalysts. Despite the tremendous research efforts in the field, many scientific questions on the role of various active sites in governing CO2RR activity, selectivity, stability, and pathways are still unanswered. These gaps in knowledge are highlighted and a discussion is set forth on the merits of utilizing advanced in‐situ and operando characterization techniques and machine learning (ML). Using this technique, the underlying mechanisms can be discerned, and as a result new strategies for designing active sites may be uncovered. Finally, this review advocates an interdisciplinary approach to discover and design CO2RR active sites (rather than focusing merely on catalyst activity) in a bid to stimulate practical research for industrial application.
