Abstract
Among all CO2 reduction reaction (CO2RR) active metals, copper is the only one that exhibits optimal *CO binding energy for multiple electron transfers. Despite such a unique feature, the use of Cu-based CO2RR catalysts at the industrial scale is hampered by large overpotentials and poor selectivity. In this realm, the introduction of acidic/basic functionalities at the catalyst surface may help to both overcome scaling relations (i.e., lower CO2RR overpotential) and tune the selectivity of Cu-based catalysts. Herein, we demonstrate that an amphoteric calcium phosphate additive (hydroxyapatite, HAP, Ca10(PO4)6(OH)2) alters the product distribution from Cu-based catalysts by steering CO2RR selectivity toward liquid oxygenated products, promoting formate production over CO.

期刊介绍：
ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format.
ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology.
The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
