Abstract Cubic phase CsPbI 3 (α‐CsPbI ) perovskite quantum dots (QDs) have received extensive attention due to their all‐inorganic composition and suitable band gap (1.73 eV). However, α‐CsPbI QDs might convert δ‐CsPbI (orthorhombic with indirect of 2.82 eV) easy loss surface ligands. In addition, commonly used long‐chain ligands (oleic acid, OA, oleylamine, OLA) hinder efficient charge transport in optoelectronic devices. order relieve these drawbacks, OLA, octanoic octylamine are as...
All-inorganic α-CsPbI3 perovskite quantum dots (QDs) are attracting great interest as solar cell absorbers due to their appealing light harvesting properties and enhanced stability the absence of volatile organic constituents. Moreover, ex situ synthesized QDs significantly reduce variability layer deposition process. However, incorporation into mesoporous TiO2 (m-TiO2) is highly challenging, but these constitute best performing electron transport materials in state-of-the-art cells. Herein,...
The precise construction of photocatalysts with diatomic sites that simultaneously foster light absorption and catalytic activity is a formidable challenge, as both processes follow distinct pathways. Herein, an electrostatically driven self-assembly approach used, where phenanthroline used to synthesize bifunctional LaNi within covalent organic framework. La Ni site acts optically catalytically active center for photocarriers generation highly selective CO2-to-CO reduction, respectively....
Adsorbent-assisted air water harvesting (AWH) may help alleviate the current global freshwater scarcity crisis. However, weak sorption capacity of various adsorbents and high energy required to release are two long-standing problems.

In the present work, a novel method for synthesizing one-dimensional CuO nanoneedle array was introduced; that is, first, pure copper nanocrystalline layer plated by using periodic reverse pulse plating process, and then grew upon through thermal oxidation in air. The nanoneedles were characterized scanning electron microscopy, regular high-resolution transmission microscopies, X-ray diffraction, photoelectron spectroscopy, analysis system (thermogravimetry differential calorimetry). results...
In this letter, we present a gas sensor using single ZnO nanowire as sensing unit. This nanowire-based has quick and high sensitive response to H2S in air at room temperature. It also been found that the sensitivity of nanowires could be modulated enhanced by He+ implantation an appropriate dose. A possible explanation is given based on modulation model depletion layer.
Recently, abundant active materials are developed to achieve the wearable detection of human body humidity. However, limited response signal and sensitivity restrict further application due their moderate affinity water.

We report a kind of gas sensor using ZnO nanowires as the field ionization anode. The sharp tips generate very high electric fields at relatively low voltages. sensors show good sensitivity and selectivity. Moreover, detection limitation based nanowire is about 5%. More importantly, with anode exhibits an impressive performance respect to stability anti-oxidation behavior, which are significantly better than those carbon nanotubes (CNTs) electrodes. Therefore, simple, low-cost, described...
