The identity of the rate-determining step (RDS) in electrochemical CO reduction reaction (CORR) on Cu catalysts remains unresolved because: 1) presence mass transport limitation CO; and 2) absence quantitative correlation between partial pressure (pCO ) surface coverage. In this work, we determined adsorption isotherms a broad pH range 7.2-12.9. Together with electrokinetic data, demonstrate that orders adsorbed at pCO <0.4 >0.6 atm are 1st 0th , respectively, for multi-carbon (C2+ products...
CO binding energy has been widely employed as a descriptor for effective catalysts in the electrochemical CO2 and reduction reactions (CO(2) RR), however, it yet to be determined experimentally at interfaces due lack of suitable techniques. In this work, we developed method determine standard adsorption enthalpy on Cu surfaces with quantitative surface enhanced infrared absorption spectroscopy. On dendritic -0.75 V vs. SHE, enthalpy, entropy Gibbs free were 1.5±0.5 kJ mol-1 , ≈37.9±13.4...
It is firmly believed that the electroproduction of acetate via CO2/CO electroreduction follows same C–C coupling pathway as other multicarbon (C2+) products in previously proposed mechanisms. However, this view completely contradictory to experimentally observed high CO pressure dependence formation. Herein, we propose deep mechanistic insights uncover puzzle by combining comprehensive computations and experiments. Our results elucidated can induce *CO thermo-oxidation surface *OH, where...
Finding top-k items in data streams is a fundamental problem mining. Existing algorithms that can achieve unbiased estimation suffer from poor accuracy. In this paper, we propose new sketch, WavingSketch, which much more accurate than existing algorithms. WavingSketch generic, and show how it be applied to four applications: finding frequent items, heavy changes, persistent Super-Spreaders. We theoretically prove provide estimation, then give an error bound of our algorithm. Our experimental...
Electrochemical CO2 reduction reaction (CO2RR) to multi-carbon products would simultaneously reduce emission and produce high-value chemicals. Herein, we report Cu electrodes modified by metal-organic framework (MOF) exhibiting enhanced electrocatalytic performance convert into ethylene ethanol. The Zr-based MOF, UiO-66 in situ transform amorphous ZrOx nanoparticles (a-ZrOx), constructing a-ZrOx/Cu hetero-interface as a dual-site catalyst. Faradaic efficiency of (C2+) for optimal...
A ship-in-a-bottle architecture on carbon nanotube yarn-based supercapacitor is prepared, in which transition metal hydroxide nanoparticles are confined metal–organic frameworks anchored nanotubes and exhibits ultrahigh structural electrochemical stability.
The electrochemical CO2 reduction reaction (CO2RR) on Cu occurs via two tandem steps, i.e., the CO2-to-CO conversion and CO (CORR). Thus, Cu-catalyzed CO2RR is, in fact, coelectrolysis of CO, which makes impact interfacial CORR a relevant factor determining overall performance. In this work, we report surprising observation that effect formation rate C2+ products depends nature cations electrolyte, beneficial with K+ Cs+ while inhibitory Li+ Na+. Density functional theory calculations...
This work reports a general and effective strategy of determining the intrinsic Stark tuning rate by removing impact dynamical coupling adsorbed CO on Cu surface with enhanced infrared absorption spectroscopy (SEIRAS).
CO binding energy has been employed as a descriptor in the catalyst design for electrochemical CO2 reduction reactions (CO2 RR). The reliability of yet experimentally verified due to lack suitable methods determine energies. In this work, we determined standard adsorption enthalpies ( ΔHCO∘${\Delta {H}_{CO}^{^\circ{}}}$ ) undoped and doped oxide-derived Cu (OD-Cu) samples, first time established correlation with Faradaic efficiencies (FE) C2+ products. A clear volcano shaped dependence FE...
ABSTRACT Unravelling the influence of strain and geometric effects on electrochemical reduction carbon dioxide (CO2RR) Cu-based (or Pd-based) alloys remains challenging due to complex local microenvironment variables. Herein, we employ two PdCu (nanoparticles nanodendrites) demonstrate how CO2RR selectivity can shift from CO HCOO−. Despite sharing consistent phases, exposed crystal facets, overall oxidative states, these exhibit different profiles their distinct geometries. By integrating...
Implantable neural devices that record neurons in various states, including static light activities such as walking, and vigorous running, offer opportunities for understanding brain functions dysfunctions. However, recording under remains a long-standing challenge because it leads to intense deformation. Thus, three key requirements are needed simultaneously devices, is, low modulus, specific interfacial impedance, high electrical conductivity, realize stable device/brain interfaces...
The electrocatalytic reduction of CO2 to CO is slowed by the energy cost hydrogenation step that yields adsorbed *COOH intermediate. Here, we report a hydrogen radical (H•)-transfer mechanism aids this step, enabled constructing Ni-partnered hetero-diatomic pairs, and thereby greatly enhancing CO2-to-CO conversion kinetics. partner metal Ni (denoted as M) catalyzes Volmer water/proton generate *H, turning H•, which reduces carboxyl radicals (•COOH). then subsequently adsorbs •COOH in an...
Microenvironment at electrochemical interfaces has a critical impact on the elec-trode-mediated proton-coupled electron transfer (PCET) processes. However, understanding convoluted effects by microenivornment remains challenging, and deploying tranfer theory of Marcus-Hush-Chidsey (MHC) framework is limited its elusive link to experimentally accessible variables other than reaction rates. Herein, we report general mech-anistic based MHC deconvolute microenvironment interfacial PCET processes...
