N 2 can be activated via s–d orbital synergy of AE metal active centers, i.e. , metals's orbitals share electrons with their empty d orbitals, and then the partially occupied exchange σ π* .
Double-atom catalysts (DACs) for harmful nitrate (NO3−) electroreduction to valuable ammonia (eNO3RR) is attractive both environmental remediation and energy transformation. However, the limited metal loading in most DACs largely hinders their applications practical catalytic applications. Therefore, exploring ultrahigh-density (UHD) with abundant active centers excellent eNO3RR activity highly desired under site-distance effect. Herein, starting from experimental M2N6 motif deposited on...
In this study, we explore the dynamics of a perovskite-electrolyte photoelectrochemical cell, pivotal for advancing electrolyte-gated field effect transistors, water-splitting and photocatalytic cells, supercapacitors, CO 2 capture reduction technologies. The instability hybrid perovskite materials in aqueous electrolytes presents significant challenge, yet recent breakthroughs have been achieved stabilizing organo-inorganic halide films. This stabilization is facilitated by employing liquid...
CuO nanoarrays were synthesized by using a hydrothermal method, and TiO 2 nanocrystals deposited on the surface of to form bulk heterostructure photoelectrodes. The current-time curve revealed that can enhance photocurrent nanoarrays, resulting from higher charge separation efficiency transfer rate. In addition, effects small biases (–0.1 0.1 V) photogenerated dynamics in aforementioned photoelectrodes evaluated. A bias was found not influence macroscopic dynamical process during charging...
Abstract The photoelectrochemical cell based on the perovskite-electrolyte solid-liquid junction has potential applications in electrolyte gated field effect transistors, and photocatalytic cells for water-splitting, supercapacitors, CO 2 capture reduction devices. While hybrid perovskite materials face challenges due to their instability when contact with aqueous electrolytes, there have been recent advancements achieving stability of organo-inorganic halide films by utilizing specific...
The photovoltaic conversion of heterojunction solar cells relies on the interface properties between n-type and p-type semiconductors. In this work, ternary bulk constituted by TiO2 nanoarray, ferroelectric BiFeO3 interlayer, BiOI is fabricated a solution method. Solid-state FTO/TiO2 nanoarray/BiFeO3 /BiOI/spiro-OMeTAD/Ag are constructed for first time, their photo energy performance studied. After introducing interlayer at TiO2-NA BiOI, cell open-circuit voltage ( Voc ) increases from 0.18...
The photocurrent output of the C6H4NH2CuBr2I/TiO2 heterojunction photoelectrode in an aqueous solution is super stable even after 30 000 s. However, extremely weak. Intensity-modulated spectroscopy revealed that electron transfer without bias not sufficiently fast to compete with charge recombination process due short diffusion length (∼23 nm), resulting a low photocurrent. separation and efficiency bulk C6H4NH2CuBr2I could be significantly improved under small reverse electric field (Er), enhanced
