    Abstract The discovery of new materials requires the development of a diversity of synthetic techniques. Microwave methods offer the opportunity to synthesise and modify the composition, structure and morphology of materials, particularly composites via differential heating. Microwave-induced plasmas (MIPs) allow any solid mixture to be heated, and can promote direct microwave heating at elevated temperature, greatly expanding the use of microwaves for reactions between solids and gas-solid mixtures.

    Abstract Sunlight is an abundant and clean energy source, the harvesting of which could make a significant contribution to society's increasing energy demands. Metal halide perovskites (MHP) have recently received attention for solar fuel generation through photocatalysis and solar-driven electrocatalysis. However, MHP photocatalysis is limited by low solar energy conversion efficiency, poor stability, and impractical reaction conditions. Compared to photocatalysis, MHP solar-driven electrocatalysis not only exhibits higher solar conversion efficiency but also is more stable when operating under practical reaction conditions. In this Perspective, we outline three leading types of MHP solar-driven electrocatalysis device technologies now in the research spotlight, namely, (1) photovoltaic-electrochemical (PV-EC), (2) photovoltaic-photoelectrochemical (PV-PEC), and (3) photoelectrochemical (PEC) approaches for solar-to-fuel reactions, including water-splitting and the CO

    Abstract The propagation of light in photonic materials can be modified to increase the probability of photon absorption. Here we report the synthesis of composite materials comprising a photochemically inert photonic macroporous ZrO2 support decorated with photocatalytically active CdS nanoparticles. The relative energies of valence and conduction bands restrict photon absorption and catalysis to the CdS nanoparticles. The generation of hydrogen from water under visible light illumination (>400 nm) has been studied as a function of the photonic support. A maximum 4.7 fold enhancement in hydrogen production is observed compared to a non-photonic support when the absorption band of the CdS nanoparticles partially overlaps with the blue edge of the photonic ZrO2 stop band. This general strategy supports the independent optimization of optical and photochemical processes to increase the overall conversion efficiency of solar to chemical energy.

    Abstract The structure of β-carboline, also called norharman (systematic name: 9H-pyrido[3,4-b]indole), C(11)H(8)N(2), has been determined at 110 K. Norharman is prevalent in the environment and the human body and is of wide biological interest. The structure exhibits intermolecular N-H···N hydrogen bonding, which results in a one-dimensional herringbone motif. The three rings of the norharman molecule collectively result in a C-shaped curvature of 3.19 (13)° parallel to the long axis. The diffraction data show shorter pyridyl C-C bonds than those reported at the STO-3G level of theory.

    Abstract Transparent conducting oxides (TCO's) are integral to many optoelectronic devices used for a range of display and solar energy technologies. Non-planar, 3-dimensional, TCO's offer the opportunity to support thin films of functional materials to increase light absorption, charge extraction, and wavelength-dependent manipulation of light if ordered into photonic structures. In addition increased surface area is also important for applications which rely on interfacial phenomena such as photoelectrochemical solar energy conversion, which is the focus of this investigation. Photoelectrodes have been fabricated from ordered spherical arrays of aluminium doped zinc oxide (AZO) and subsequently coated with photoactive semiconductor (CdS) nanoparticles using simple solution chemical deposition. The spheres of the structured AZO TCO are hollow and access to the internal volume supports loading of CdS as a thin film which results in increased light collection per geometric surface area. Efficient charge collection is observed, without restricting diffusion of electrolyte, allowing photocurrents ca. 20 times greater than a planar analogue.
