Rational design of catalytic sites to activate the CC bond is paramount importance advance acetylene hydrochlorination. Herein, Cu with electron-rich and electron-deficient states were constructed by controlling impregnation solutions. The π electrons flowing from site are facilitated over sites, achieving high activation bond. contradiction between increased required for enhanced activity resistance reduction maintaining stability can be balanced establishing strong interactions pyrrolic-N...
It remains challenging to achieve nanoparticles with uniform size and dispersion or single atoms identical coordination structure, although various methods have been developed synthesize carbon-supported nanostructured catalysts. Typically, in the synthesis of vinyl chloride (VCM) by acetylene hydrochlorination, a limited understanding optimal architecture for Cu catalysts at nanoscale greatly restrains their further development application. To this, single-atom (Cu-O3P) environments Cu/Cu3P...
The design of inexpensive, nontoxic, and abundant transition metal catalysts for the selective hydrogenation alkynes remains a significant challenge faced by both industrial academic communities. Here, we report novel catalyst comprising well-defined Cu–Zn dual-atom supported on defective pyrolyzed ZIF-8 material (CuZn/NC2), resulting in enhanced d-electron domination near Fermi level reordered d-orbital Splitting manner. This exhibited outstanding performance acetylene to ethylene,...
Designing favorable structures of active sites and clarifying the structure–activity relationship are important to narrow large activity gap between Cu-based noble-metal-based catalytic systems for vinyl chloride production. Herein, we report a facile controllable thermal method fabricating platform Cu single-atom catalysts ranging from standard no-vacancy-defect CuCl3–N vacancy-defect CuCl2V–N ("V" site) CuN4. The gradually released C–Cl derivatives promote generation under elevated...
Vinyl chloride, the monomer of polyvinyl chloride (PVC), is industrially synthesized via acetylene hydrochlorination. Thereby, easy to sublimate but toxic mercury catalysts are widely used. It imperative find environmentally friendly non-mercury promote green production PVC. Low-cost copper-based promising candidates. In this study, phosphorus-doped Cu-based prepared. shown that type phosphorus configuration and distribution on surface carrier can be adjusted by changing calcination...
Catalysis involving gold supported on metal oxides has undergone extensive examination. However, the nature of catalytic site under actual reaction conditions and role support continue to be vigorously debated. This study addresses these issues through experimental investigations theoretical simulations. We explore a novel mechanism that employs dynamic single-atom catalysis for hydrochlorination acetylene. occurs in defective ZrO2-supported Au–Zr alloys. Specifically, is result mobility...
Non-mercuric catalysts in acetylene hydrochlorination reaction have been gained much attention.
In the process of acetylene hydrochlorination, rapid deactivation supported gold (Au) catalysts by is still a huge challenge. Here, we provide an innovative strategy for constructing acetylene–deficient reaction phase on active site coating ionic liquid film Au(H2O)/C surface. The reactant ratio C2H2 to HCl in this 1:132, contrast 1:1 M gas phase, thus boosting catalytic stability catalysts. kinetic and theoretical analysis showed that reduction cationic generation carbon deposition can be...
Abstract Nitrogen‐doped carbons supported gold catalysts has attracted much attention in a broad range of applications. However, co‐existence multiple nitrogen species which may have vastly different effect on the gold‐based catalysts, limited development an ideal nitrogen‐doped carbon support. Herein, we demonstrated that by addition sulfur species, selective formation pyrrolic against pyridinic can be achieved for doped The synthesized from support produced using ionic liquid‐assisted...
Ru-Based catalysts with distinct active phases from Ru0, to RuO2, RuCl3 and RuCl2N were synthesized evaluated in acetylene hydrochlorination. is identified as the efficient phase due its co-activation of hydrogen chloride.

Acetylene hydrochlorination is an attractive chemical reaction for the manufacture of polyvinyl chloride (PVC), and development efforts are focused on search non-mercury catalyst systems. Supported Pd-based catalysts have relatively high activity in catalytic acetylene but still deactivated rather quickly. Herein, we demonstrated that atomically dispersed (NH4)2PdCl4 complex, distributed activated carbon, enabled highly active stable production vinyl monomer (VCM) through under low...
In this study, the typical oxidation process of Au/C catalysts exposed to HCl is presented. Although violates standard electrode potentials, "oxidized" tendency Au(0) species analyzed. This behavior can only be triggered over sample within residual cationic Au species, and terminated completely metallic Au(0)/C sample. study demonstrates that presence surface chlorination cannot facilitate Au(I) when treated with alone, which excludes paths of: → Au(III) Au(III). The reported "HCl-oxidized...
An efficient and stable heterogeneous Zeolite Supported Ionic Liquid Catalyst (IL/CaX) has been explored in acetylene hydrochlorination reaction. The IL/CaX catalyst exhibits excellent space time yields of vinyl chloride (VCM), when compared to the benchmark Au/C systems. Through characterization kinetic studies, reaction follows a two-site mechanism, which is described as adsorbed hydrogen on Ca2+ zeolite, reacting with cation ionic liquid form chloride. catalytic takes place at interface,...
