The morphology engineering represents an alternative route toward efficient hematite photoanodes for photoelectrochemical (PEC) water splitting without changing the chemical composition. In this work, a facile and mild solvothermal synthesis of unique ferrihydrite branched nanosheet arrays vertically aligned on FTO substrate was achieved at around 100 °C.(More)
Hierarchical structures (HSs) constructed by nanoparticle-based building blocks possess not only the properties of the primary building blocks but also collective properties of the assemblies. Here we report the facile preparation of hierarchical Ag nanoparticles/polyhedral oligomeric silsequioxane molecule (POSS) hybrid branched structures within tens of(More)
Unique spindle-shaped nanoporous anatase TiO(2) mesocrystals with a single-crystal-like structure and tunable sizes were successfully fabricated on a large scale through mesoscale assembly in the tetrabutyl titanate-acetic acid system without any additives under solvothermal conditions. A complex mesoscale assembly process involving slow release of soluble(More)
The formation of conductive micropatterns via laser direct writing using metal nanoparticle ink was studied toward 3D interconnection. Copper (Cu) micropatterns were fabricated by laser irradiation on a precursor film prepared via spin-coating of a Cu nanoparticle ink on a substrate. A focused laser beam was scanned on the copper nanoparticle film using a(More)
This study reports the laser direct writing of graphene oxide (GO) to form reduced graphene oxide (RGO)-GO-RGO interdigitated on-chip micro-supercapacitors (MSCs) by reducing GO to RGO. The resolution of the laser writing lines can be lowered to 10 &#x03BC;m, which is much lower than that formed by the CO<sub>2</sub> pulse laser, suggesting the potential to(More)
The supramolecular ionic self-assembly (ISA) strategy has been used to construct the long-range ordered hierarchical aggregates from the complexes of 1-adamantanamine hydrochloride (AdCl) and sodium bis(2-ethyl-1-hexyl)sulfosuccinate (AOT). The formed AOT-Ad complexes have been proved to possess a composition of equal molar ratio and a hexagonal columnar(More)
