NO2 gas sensors based on metal oxides under wild conditions are highly demanded yet an incomplete surface reaction and humidity interference the gas-sensing performance limit their applications. Herein, we report three-dimensional (3D) porous In2O3 microcubes via a simple hydrothermal strategy to produce outstanding performance: fast equilibrium of at 150 °C negligible dependence sensing room temperature. The 3D with high areas, suitable pore sizes, rich oxygen vacancies, conductivity...
The two-dimensional (2D) defect-enriched nanomaterials have aroused great interests, owing to its special electronic properties and the fast transport of lithium ions. Herein, we present a facile mature method cage SiOx nanoparticles into graphite flake through ball-milling for 4 h (GF-4), assisted by solid diluent 4-aminophenol (4-AP). 4-AP prevents reaggregation flakes excessive formation defect carbon during milling process. Moreover, it further consolidates layered sandwiching structure...
Silicon oxide (SiOx, 0 < x 2) is considered one of the most promising anode materials for next-generation lithium-ion batteries due to its high theoretical capacity. However, commercial application limited by non-negligible volume change during cycling. Herein, a three-dimensional (3D) structure carboxymethyl cellulose (CMC) cross-linked with iminodiacetic (c-CMC-IDA150) was facilely formed through in situ thermal cross-linking CMC and acid (IDA) fabrication process electrode, which could...
In this study, Ag nanoparticles with diverse particle size and concentration, fabricated via the polyol method, were embedded in a TiO2 compact film to improve power conversion efficiency of perovskite solar cells. Obtained results showed that do not affect crystal structure TiO2, while can strongly influence light absorption capacity materials. However, intensity cells decreased increase nanoparticles. The amount was also an important factor for performance cells, layer optimized measure 10...
Au@Pt@Au core-shell nanoparticles, synthesized through chemical reduction, are utilized to improve the photoelectric performance of perovskite solar cells (PSCs) in which carbon films used as counter electrode, and hole-transporting layer is not used. After a series experiments, these nanoparticles optimized demonstrate outstanding optical electrical properties due their local surface plasmon resonance scattering effects. PSC devices containing 1 wt.% have highest efficiency; this...
In this work, NaEuF4 nanoparticles (NPs) with high dispersity and uniformity were synthesized using a hydrothermal method introduced into the TiO2 mesoporous layer of perovskite solar cells (PSCs) for testing as efficiency, downconversion materials. can convert high-energy photons low-energy absorption by CH3NH3PbI3 generation more electron–hole pairs; we tested hypothesis that would extend sunlight range improve photovoltaic performance PSCs. When NPs incorporated layers, PSCs achieved...
Non-negligible volume change is a troublesome problem for the commercial application of silicon oxide (SiOx). It acknowledged that polymer binders' design promising method to promote commercialization SiOx. Herein, we proposed three-dimensional (3D) dynamic cross-linked binder (CS-EDTA) via ionic bonding between chitosan (CS) and ethylenediaminetetraacetic acid (EDTA). With excellent adhesive strength, CS-EDTA could tighten connection electrode constituents prevent delamination. Due...
As an important part of perovskite solar cells (PSCs), the compact electron transport layer largely determines performance devices. Titanium dioxide (TiO 2 ) and tin (SnO are very common materials for (ETL) in PSCs. However, less has been reported regarding development high efficiency mesoporous PSCs based on a SnO layer. Herein, we prepared Mg doped modified film at temperature, combined it with TiO to form composite layer, then applied structure. Compared pristine excellent interface...
