CO is a useful product of CO<sub>2<\/sub>&nbsp;reduction, but conventional production methods require high temperatures and substantial energy input. A promising alternative is to use catalysts that harness mechanical energy, such as vibration, to drive chemical reactions under mild conditions, although their efficiency and product selectivity for CO<sub>2<\/sub>&nbsp;conversion have remained limited.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/www.sanken.osaka-u.ac.jp\/staging\/assets\/research\/Research_260423_Kondo_01.jpg\" alt=\"Schematic images of piezocatalytic CO2 reduction over Ni single-atom anchored on N-doped carbon deposited on BaTiO3.\nLicense\uff1aLicensed content\nUsage restriction: Credit must be given to the original publication: https:\/\/doi.org\/10.1039\/D5TA09053A\nCredit: Yoshifumi Kondo and Tohru Sekino from J.

By depositing nitrogen-doped carbon containing atomically dispersed nickel on BaTiO3 nanocubes, the researchers created a material that efficiently reduced CO<sub>2<\/sub>&nbsp;to CO under ultrasonic vibration at room temperature and ambient pressure.<\/p>\n\n\n\n<p>In five hours of sonication, the new catalyst produced 377 mmol g\u22121 of CO, compared with 123 mmol g\u22121 for pristine BaTiO<sub>3<\/sub>, corresponding to a 3.1-fold improvement. No H2, CH4, or HCOOH were detected as carbon-reduction products under the tested conditions, indicating almost 100% selectivity for CO among the detected carbon products.<\/p>\n\n\n\n<p>The study also clarified why the catalyst performed so well. The nitrogen-doped carbon helped promote charge separation and transfer, while the isolated nickel single-atom sites acted as highly active centers for CO<sub>2<\/sub>&nbsp;reduction. Structural analysis showed that the nickel atoms were atomically dispersed in a Ni-N4 configuration within the carbon layer. The catalyst also remained stable over repeated cycles, suggesting that the nickel sites were firmly anchored during operation.&nbsp;<\/p>\n\n\n\n<p>The work provides a new design strategy for combining piezoelectric materials with single-atom catalytic sites, opening a possible path toward sustainable CO<sub>2<\/sub>&nbsp;conversion using underutilized mechanical energy. Dr. Yoshifumi Kondo, senior author of the study, commented, \u201cEstablishing technologies to recycle industrially emitted CO<sub>2<\/sub>&nbsp;is essential for achieving carbon neutrality. In this work, we clarified part of the design guideline for reaction-active sites in piezocatalytic CO<sub>2<\/sub>&nbsp;reduction. Going forward, we hope to develop new low-energy CO<sub>2<\/sub>&nbsp;conversion methods that make use of underutilized energy, such as mechanical vibration and waste heat.\u201d&nbsp;<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/www.sanken.osaka-u.ac.jp\/staging\/assets\/research\/Research_260423_Kondo_02_EN.jpg\" alt=\"Fig. 2 : CO production rates of developed catalysts under ultrasonic vibration.\" style=\"width:529px;height:auto\"\/><figcaption class=\"wp-element-caption\">Fig. 2 : CO production rates of developed catalysts under ultrasonic vibration. \u00a9 Yoshifumi Kondo, Tohru Sekino<\/figcaption><\/figure><\/div>\n\n\n<div style=\"height:19px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Article Information\">Original Publication<\/h3>\n\n\n\n<p><strong>Title:\u00a0<\/strong>Ni single-atom doped N-doped carbon deposited on BaTiO<sub>3<\/sub>\u00a0for efficient piezocatalytic CO<sub>2<\/sub>\u00a0reduction; <strong>Journal:\u00a0<\/strong><em>Journal of Materials Chemistry A<\/em>; <strong>Authors:\u00a0<\/strong>Jing Cao, Yoshifumi Kondo, Yeongjun Seo, Tomoyo Goto, and Tohru Sekino; <strong>DOI:\u00a0<\/strong><a href=\"https:\/\/doi.org\/10.1039\/D5TA09053A\">10.1039\/D5TA09053A<\/a><\/p>\n\n\n\n<div style=\"height:18px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Funded by:<\/strong><\/h3>\n\n\n\n<div style=\"height:14px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Japan Society for the Promotion of Science<\/li>\n\n\n\n<li>Ministry of Education, Culture, Sports, Science and Technology<\/li>\n\n\n\n<li>Kazuchika Okura Memorial Foundation<\/li>\n\n\n\n<li>Tokuyama Science Foundation<\/li>\n<\/ul>\n\n\n\n<div style=\"height:18px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at The University of Osaka have developed a catalyst that uses vibrational energy to convert carbon dioxide (CO2) into carbon monoxide (CO), an important industrial feedstock.
