We demonstrate highly-efficient, solution-processed small molecule solar cells with the best power conversion efficiency (PCE) of more than 5%. The active layer consists of a diketopyrrolopyrrole-based donor molecule (DPP(TBFu)2) and a fullerene derivative (PC71BM) that is spin cast and subsequently treated with solve…
3D nanoflower-like CuxO/multilayer graphene composites (CuMGCs) have been successfully synthesized as a new type of room temperature NOx gas sensor. Firstly, the expanded graphite (EG) was activated by KOH and many moderate functional groups were generated; secondly, Cu(CH3COO)2 and CTAB underwent full infusion into t…
Copper zinc tin sulfide (CZTS) is an emerging photovoltaic material comprised of earth abundant elements. Presence of very small amounts of sodium and potassium during the synthesis of thin CZTS films enhances grain growth and leads to microstructures ideally suited for solar cells.
Systematic development of Fe–Ni bimetallic carrier results in efficient and safe chemical looping process for methane partial oxidation to syngas.
Formamidinium (FA) lead triiodide perovskite with chlorine addition (NH2CH=NH2PbI(3-x)Clx) is employed as a light harvester in mesoscopic solar cells for the first time. It is demonstrated that a phase-pure FAPbI(3-x)Clx perovskite layer can be synthesized using a one-step solution-process at 140 °C, and the resultant…
A two-step procedure for the post-synthetic preparation of Lewis acidic Sn-, Zr- and Ti-zeolite β is reported. Dealumination of a commercially available Al-β zeolite leads to the formation of highly siliceous material containing silanol nests, which can be filled in a second step via the solid-state ion-exchange or im…
An artful graphene sheltering engineering onto TiO2 nanotube array for perfect inhibition of CdS photocorrosion (RGO/CdS-TiO2 NT) has been developed by a one-step electrodeposition method. The CdS photocorrosion driven by both holes and radicals has been systematically investigated and identified. The RGO layer provid…
A cobalt catalyst is very efficient and stable for hydrogenation of biomass-derived ethyl levulinate to gamma-valerolactone under mild conditions.
A facile, fast, non-destructive and roll-to-roll compatible photochemical method for simultaneous partial reduction and doping of graphene oxide (GO) films through ultraviolet laser irradiation in the presence of a Cl2 precursor gas is demonstrated. The photochemical chlorinated GO-Cl films were fully characterized by…
WN nanoparticles of 2–3 nm are grown on graphene, which can be used as promising carriers for methanol electro-oxidation.
Si-based anodes in lithium ion batteries (LIBs) have exceptionally high theoretical capacity, but the use of a Si-based anode in LIBs is problematic because the charging-discharging process can fracture the Si particles. Alginate and its derivatives show promise as Si particle binders in the anode. We show that calciu…
Recent progress of energy storage systems based on neutral aqueous electrolytes provides some quite green chemistries with promising applications in electric vehicles and smart grids.
This study provides new insights into the interplay of water as a co- and/or anti-solvent during ionic liquid (IL) pretreatment of lignocellulose.
Uniform co-doping of nitrogen and sulfur on graphene effectively catalyzes the triiodide reduction, resulting in high conversion efficiency of DSSCs.
This paper summarizes the applications of V O s-induced structural disorders of core-shell C/TiO 2 and reduced TiO 2 in improving solar-driven photocatalytic activities.
Despite their extremely low solubility in most solvents, hexagonal grey selenium and tellurium are shown to be remarkably soluble in binary mixtures of thiols and ethylenediamine (en) at room temperature and ambient pressure. A 1 : 4 vol/vol mixture of ethanethiol (EtSH) and en gave saturated solutions of 38 and 9.3 w…
In this research work an effort has been made to prepare hybrid aluminium metal matrix composite to study its machining and mechanical properties. Preparation of hybrid aluminium metal matrix composite is made by reinforcing Silicon carbide and Titanium di boride. Morphology of the composite and reinforced particle di…
Widespread adoption of solar-thermochemical fuel production depends on its economic viability, largely driven by the efficiency of use of the available solar resource. Herein, we analyze the efficiency of two-step cycles for thermochemical hydrogen production, with emphasis on efficiency. Owing to water thermodynamics…
In this study, we report on a novel potential-responsive hybrid film system for heavy metal removal, which was composed of a layered α-zirconium phosphate (α-ZrP) nanosheet and a conducting polyaniline (PANI)-intercalated chain that functioned as a proton pumping element. The proposed system features a quick responsiv…
A two-dimensional (2D) SnNb2O6 nanosheet-graphene (SnNb2O6-GR) nanocomposite featuring a typical 2D-2D structure has been synthesized via a simple surface charge modified self-assembly approach. The method is afforded by electrostatic attractive interaction between negatively charged SnNb2O6 nanosheets and modified gr…
