Abstract

Understanding the decisive factors of electrochemical reactions and developing the effective manipulation strategies are crucial for the rational design of highly active catalysts and renewable energy conversion technologies. In this...

Recent progress in group-III metal chalcogenide based Janus materials: from properties to potential applications

“…In particular, how to use the intrinsic dipole to construct a multifunctional material, i.e. , memory and electronic devices, 105,106 multiferroics, 107,108 ferroelectric controlled ON–OFF catalysts, 109,110 etc. , should be investigated in the near future.…”

“…(iv) While the role of the intrinsic dipole was found to be highly important, the generalized rule that the intrinsic dipole affects the physical properties and the applications is still uncertain. In particular, how to use the intrinsic dipole to construct a multifunctional material, i.e., memory and electronic devices, 105,106 multiferroics, 107,108 ferroelectric controlled ON-OFF catalysts, 109,110 etc., should be investigated in the near future.…”

Van der Waals Ferroelectrics: Theories, Materials, and Device Applications

“…The modulation of adsorption energies and electron transfer occurs through the reversal of polarization, inducing electron redistribution, changes in magnetic moments, and shifts in band states near the Fermi level. [ 193 ] Calculations indicate that the catalytic performance in single‐atom catalysis of CO oxidation using a Pt/In 2 Se 3 monolayer can also be effectively regulated by ferroelectric switching. [ 194 ] The intrinsic electric fields in 2D M 2 X 3 (M = Al, Ga, In; X = S, Se, Te) ferroelectric materials boost the solar‐to‐hydrogen efficiency for photocatalytic water splitting.…”

The regulatory function of the d-orbital structure in TM@g-t-C4N3 for bifunctional catalysis of the oxygen evolution/reduction reaction

“…15,16 Single-atom catalysts (SACs) have been considered to have broad prospects in catalysis owing to the maximized utilization of loaded metal atoms and the excellent catalytic activity. 17,18 Numerous studies have revealed the commendable catalytic ability of SACs for a series of reactions, such as the OER, [19][20][21] ORR, [22][23][24] hydrogen evolution reaction (HER), [25][26][27][28] nitrogen reduction reaction (NRR), 29,30 carbon dioxide reduction reaction (CO 2 RR), 31,32 etc. In order to acquire a SAC structure with sufficiently dispersed transition metal (TM) atoms, a suitable substrate is firstly required, which should restrain the aggregation of loaded TM atoms.…”
