“…Recently, amorphous catalysts have exhibited unique structural and chemical properties, becoming promising electrocatalytic candidates and receiving a growing interest and potential in oxygen evolution reaction (OER), hydrogen evolution reaction (HER), oxygen reduction reaction (ORR), carbon dioxide reduction reaction (CO 2 RR), nitrogen reduction reaction (NRR), and so on [28][29][30][31][32] . The tunability in composition, morphology, active sites, and surface properties provides an attractive platform to improve catalytic activity, stability, and selectivity.…”

Amorphous materials feature unique structures and physicochemical properties, resulting in their synthesis and applications becoming a dynamic and fascinating new research direction. The high specific surface area, abundant active sites, and good electron transport properties endow amorphous materials with excellent electrocatalytic properties, thus appealing to increasing attention. Based on this, the summary of the current research status of amorphous catalysts in the field of electrocatalysis is urgent and important. In this review, the research progress of amorphous catalysts in electrocatalysis is systematically introduced, focusing on the classification, synthesis methods, modification strategies, characterizations, and electrocatalytic application (including hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, carbon dioxide reduction reaction, and nitrogen reduction reaction). Finally, this review proposes the prospects and challenges for the future development of high-active and high-selectivity amorphous electrocatalysts.

“…Among metal-based materials for electrochemical CO 2 reduction into formate, , Bi-based electrocatalysts have emerged as the most promising candidate. , In addition to inherent catalytic performance, abundant reserves, and nontoxicity, Bi-based materials also can inhibit the competition of the hydrogen evolution reaction (HER) in the CO 2 reduction process. − Generally speaking, the fabrication of highly active metallic Bi catalytic centers usually includes the in situ reduction of Bi-based precursors during the CO 2 reduction reaction. For instance, Bi ultathin nanosheets dotted with abundant pit sites can be derived from Bi(OH) 3 and exhibited a high catalytic activity toward formate production .…”

Electroreduction of carbon dioxide into readily collectable and highvalue carbon-based fuels is greatly significant to overcome the energy and environmental crises yet challenging in the development of robust and highly efficient electrocatalysts. Herein, a bismuth (Bi) heterophase electrode with enriched amorphous/crystalline interfaces was fabricated via cathodically in situ transformation of Bi-based metal-phenolic complexes (Bi-tannic acid, Bi-TA). Compared with amorphous or crystalline Bi catalyst, the amorphous/crystalline structure Bi leads to significantly enhanced performance for CO 2 electroreduction. In a liquid-phase H-type cell, the Faraday efficiency (FE) of formate formation is over 90% in a wide potential range from −0.8 to −1.3 V, demonstrating a high selectivity toward formate. Moreover, in a flow cell, a large current density reaching 600 mA cm −2 can further be rendered for formate production. Theoretical calculations indicate that the amorphous/crystalline Bi heterophase interface exhibits a favorable adsorption of CO 2 and lower energy barriers for the rate-determining step compared with the crystalline Bi counterparts, thus accelerating the reaction process. This work paves the way for the rational design of advanced heterointerface catalysts for CO 2 reduction.
