(1) \u003cstrong\u003eSelective Adsorption\u003c\/strong\u003e: The nitrogen atoms in the triazole ring have lone pairs that coordinate strongly with metal surfaces. The phenyl group provides a hydrophobic \"tail.\" Together, they form a self-assembled or loosely organized layer on the cathode. (2) \u003cstrong\u003eProton Shielding\u003c\/strong\u003e: By covering active sites with a hydrophobic organic layer, the additive physically blocks water molecules (H2O) from reaching the catalyst surface. This effectively starves the HER, which requires water as a proton source. (3) \u003cstrong\u003eIntermediate Stabilization\u003c\/strong\u003e: The triazole ring can interact with CO reduction intermediates (like *COOH or *CO) through dipole-dipole interactions or hydrogen bonding, lowering the activation energy for CO2 conversion.\u003c\/p\u003e\n\u003cp\u003eThe use of 4-phenyl-1,2,3-triazole is typically targeted at improving Faradaic Efficiency (FE) for C1 products. (1) Shifts performance toward Carbon Monoxide (CO) or Formate. (2) Reduce H2 production from \u0026gt;50% to \u0026lt;10% on certain catalysts. (3) Often allows for CO2 reduction at lower (more positive) potentials by stabilizing polar intermediates. (4) The phenyl-triazole bond is electrochemically robust, preventing the additive from degrading rapidly under high negative bias.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 192.637px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.2375px;\"\u003e\n\u003ctd style=\"width: 35.0575%; height: 40.2375px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 40.2375px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCO2RREAPhTA (C-CO2RR-EA-PhTA)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e1680-44-0\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eChemical Formula\/Structure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cspan\u003eC\u003c\/span\u003e\u003csub\u003e8\u003c\/sub\u003e\u003cspan\u003eH\u003c\/span\u003e\u003csub\u003e7\u003c\/sub\u003e\u003cspan\u003eN\u003c\/span\u003e\u003csub\u003e3\u003c\/sub\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CCO2RREAPhTA_molecular_structure_160x160.png?v=1771951596\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 35.0575%; height: 35.6px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eWhite to light yellow powder\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e145.16\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003eMelting Point\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e120-121 ℃\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 35.0575%;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.7626%;\"\u003e\n\u003cp\u003e\u003cspan\u003e1 g\/bottle\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e(1）\u003ca href=\"https:\/\/pubs.acs.org\/doi\/10.1021\/jacs.5c11829?ref=recommended\"\u003eY.
