NaNbO 3 with cubic–orthorhombic surface-phase junctions were synthesized via a polymerized complex method. Improved charge separation meant that the mixed-phase NaNbO 3 exhibited much higher activity in CO 2 photoreduction than cubic and orthorhombic NaNbO 3 .
A review of synthetic routes to tin chalcogenides and CTZS, promising materials for sustainable photovoltaics.
Here, we report dicyanopyrazine (DPZ)-derived push–pull chromophores, easily prepared and tunable organic compounds, as new kinds of photoredox catalysts.

Hydrogen (H2) is a clean, portable and potentially inexhaustible energy source with the potential to become a panacea for clean energy generation. However, H2 has wide explosive concentration range (4–75 vol%), low ignition energy (0.02 mJ) and large flame propagation velocity. Due to its ultra small molecular size, c…
The synthesis of a mesoporous material with uniform mesopore diameters and crystalline MFI zeolite walls has been achieved, simply by seeding the multiammonium surfactant-directed synthesis with bulk zeolite crystals. The bulk seeds disappeared in the final product. As a result of seeding, the mesoporous zeolites coul…
Monomers structurally resembling lignin were prepared by reacting 4-hydroxybenzaldehyde, vanillin, syringaldehyde, (each bio-available) or ethylvanillin (synthetic) with dibromoethane, yielding dialdehydes CHO–Ar–OCH2CH2O–Ar–CHO. Condensation copolymerization with tetraols catalyzed by para-toluene sulfonic acid yield…
Novel poly(ether ether ketone) (PEEK) based nanocomposites with different contents of ZnO nanoparticles were prepared via cryogenic ball-milling followed by compression moulding. The nanoparticles were treated with a silane coupling agent to improve their dispersion and interfacial adhesion with the matrix. The morpho…
The environmentally friendly and low cost green synthesis of highly reduced graphene oxide using P. glutinosa
A highly selective colorimetric chemosensor LX was described, which could instantly detect Ni 2+ without interference by other cations.
UIO-66 nanoparticles with octahedral morphology and a high surface area have been prepared quickly and in high-yield by an additive/microwave method.
A series of nanometric isoreticular and/or functionalized analogues of the mesoporous environmentally-friendly iron(III) polycarboxylates MIL-100/101 have been successfully synthesized. Their exceptional pore size, of up to 68 Å, together with their relatively good stability in solvents, makes them promising candidate…
The working principle of semiconductor:insulator blends are discussed, examining the different approaches that have recently been reported in literature.
The interaction between light and matter is the fundamental aspect of many optoelectronic applications. The efficiency of such devices is mainly dictated by the light emitting properties of fluorophores. Unfortunately, the intensity of emission is adversely affected by surface defects, scattering and chemical instabil…
The water-stable frameworks, [Zr6O4(OH)4(X)6(btc)2]·nH2O, where X = formate, acetate, or propionate, exhibit tunable porosity by virtue of systematic modulation of the chain length of the monocarboxylate ligand X.
The cured bio-epoxy resins synthesized from low molecular weight tree bark extractives displayed good mechanical and thermal properties.
Materials that alloy with lithium (Si, Ge, Sn, Sb, and P) are considered as alternatives to graphitic anodes in lithium-ion batteries. Their practical use is precluded by large volume changes (200–370%) during cycling. Embedding nanoparticles into carbon is being investigated as a way to tackle that, and ball milling…
MoS 2 nanoflake array films on different glass substrates were fabricated by an in situ growth method. The nonlinear absorption (NLA) properties of the MoS 2 nanoflake array films were investigated by an open-aperture Z-scan technique. The films exhibited different NLA properties dependent on the input energy.
The poor ion conductivity of LiAlO 2 can be drastically enhanced via the introduction of defects or amorphisation during high-energy ball milling.
We pushed back the limits of molar mass control in aqueous RAFT/MADIX polymerisation through a fast and quantitative gel polymerisation of a series of acrylamido monomers. Unprecedentedly high Mn up to 106 g mol−1 with low dispersities (Đ < 1.2) was achieved in homopolymerisation, statistical and block copolymerisatio…
