A common challenge for electrochemical ammonia synthesis in an aqueous phase is the consumption of Faradaic charge by competing hydrogen evolution reaction (HER), which reduces efficiency desired conversion, i.e., nitrate reduction (NO3RR) to ammonium. This problem particularly severe when a single-phase catalyst operated at high current limits, thus cocatalyst system that works synergistically acquisition and deoxygenation needed promote NO3RR over HER. Herein, we select well-known HER Mo2C...
Abstract The photovoltaic effect lies at the heart of eco-friendly energy harvesting. However, conversion efficiency traditional utilizing built-in electric in p-n junctions is restricted by Shockley-Queisser limit. Alternatively, intrinsic/bulk (IPVE/BPVE), a second-order nonlinear optoelectronic arising from broken inversion symmetry crystalline structure, can overcome this theoretical Here, we uncover giant and robust IPVE one-dimensional (1D) van der Waals (vdW) grain boundaries (GBs)...
The conversion of excess carbon dioxide (CO2) into valuable chemicals is critical for achieving a sustainable society. Among various catalysts, molybdenum disulfide (MoS2) has demonstrated potential CO2 hydrogenation to methanol. However, its catalytic activity yet be fully optimized, and scalable, industrially viable production methods remain underdeveloped. In this work, chemical vapor deposition (CVD) approach introduced grow vertically oriented MoS2 crystals on an amorphous template....
Abstract Two new bithiophene imide (BTI)‐based n‐type polymers were synthesized. f‐BTI2‐FT based on a fused BTI dimer showed smaller band gap, lower LUMO, and higher crystallinity than s‐BTI2‐FT containing connected through single bond. exhibited remarkable electron mobility of 0.82 cm 2 V −1 s , further improved 1.13 in transistors. When blended with the polymer donor PTB7‐Th, f‐BTI2‐FT‐based all‐polymer solar cells (all‐PSCs) attained PCE 6.85 %, highest value for an all‐PSC not...
Imide-functionalized arenes, exemplified by naphthalene diimides (NDIs), perylene (PDIs), and bithiophene imides (BTIs), are the most promising building blocks for constructing high-performance n-type polymers. In order to reduce steric hindrance associated with NDI- PDI-based polymers address high-lying LUMO issue of BTI-based polymers, herein a highly electron-deficient imide-functionalized bithiazole, N-alkyl-5,5′-bithiazole-4,4′-dicarboximide (BTzI), was successfully synthesized via an...
Narrow bandgap (1.37-1.46 eV) polymers incorporating a head-to-head linkage containing 3-alkoxy-3'-alkyl-2,2'-bithiophene are synthesized. The enables with sufficient solubility and the noncovalent sulfur-oxygen interaction affords high degree of backbone planarity film ordering. When integrated into polymer solar cells, show promising power conversion efficiency approaching 10%.
Reducing particle size in supported metal catalysts to single-atom level isolates the active sites and maximizes atomic utilization efficiency. However, large inter-atom distance, particularly low-loading catalyst (SAC), is not favorable for a complex reaction where two (or more) reactants have be activated. A key question how control distances promote dinuclear-type coactivation at adjacent sites. Here, it reported that reducing average distance of copper SACs on carbon nitride (C3 N4 )...
Abstract Like phosphorene, phosphorene nanoribbon (PNR) promises exotic properties but unzipping into edge‐defined PNR is non‐trivial because of uncontrolled cutting along random directions. Here a facile electrochemical strategy to fabricate zigzag‐edged PNRs in high yield (>80%) reported. The presence chemically active zigzag edges allows it spontaneously react with Li form + ion conducting 3 P phase, which can be used as protective layer on metal anode lithium batteries (LMBs)....
Abstract The production of high‐value chemicals by single‐atom catalysis is an attractive proposition for industry owing to its remarkable selectivity. Successful demonstrations date are mostly based on gas‐phase reactions, and reports liquid‐phase relatively sparse the insufficient activation reactants catalysts (SACs), as well as, their instability in solution. Here, mechanically strong, hierarchically porous carbon plates developed immobilization SACs enhance catalytic activity stability....
The reduced symmetry in strong spin-orbit coupling materials such as transition metal ditellurides (TMDTs) gives rise to non-trivial topology, unique spin texture, and large charge-to-spin conversion efficiencies. Bilayer TMDTs are non-centrosymmetric have topological properties compared monolayer or trilayer, but a controllable way prepare bilayer MoTe2 crystal has not been achieved date. Herein, we achieve the layer-by-layer growth of large-area trilayer 1T' single crystals...
Single-atom catalysts (SACs) offer many advantages, such as atom economy and high chemoselectivity; however, their practical application in liquid-phase heterogeneous catalysis is hampered by the productivity bottleneck well catalyst leaching. Flow chemistry a well-established method to increase conversion rate of catalytic processes, SAC-catalysed flow packed-bed type reactor disadvantaged low turnover number poor stability. In this study, we demonstrate use fuel cell-type stacks enabled...
Bulk photovoltaic effect (BPVE), a second-order nonlinear optical governed by the quantum geometric properties of materials, offers promising approach to overcome Shockley-Quiesser limit traditional and further improve efficiency energy harvesting. Here, we propose an effective platform, nano edges embedded in assembled van der Waals (vdW) homo- or hetero-structures with strong symmetry breaking, low dimensionality abundant species, for BPVE investigations. The BPVE-induced photocurrents...
Abstract Materials showing second-order nonlinear transport under time reversal symmetry can be used for Radio Frequency (RF) rectification, but practical application demands room temperature operation and sensitivity to microwatts level RF signals in the ambient. In this study, we demonstrate that BiTeBr exhibits a giant response which persists up 350 K. Through scaling analysis, show skew scattering is dominant mechanism. Additionally, sign of electrically switched by tuning Fermi energy....
Abstract Enhancing the device electroluminescence quantum efficiency ( EQE EL ) is a critical factor in mitigating non-radiative voltage losses V NR and further improving performance of organic solar cells (OSCs). While common understanding attributes OSCs to dynamics charge transfer (CT) states, persistent efforts manipulate these decay have yielded limited results, with high-efficiency typically remaining below 10 −2 %. This value considerably lower than that observed high inorganic...
