Discovery of a New Catalyst for Photocatalytic Hydrogen Production: Parallel Ink-jet Printing Synthesis of Multicomponent Mesoporous Metal Oxides Library
Abstract:We introduce an ink-jet printing technique for fabricating Multicomponent Mesoporous Metal Oxides (MMMOs). The properties of the precursors and organic templates, and sol–gel/mesostructure co-assembly process can be controlled to meet the demand of ink-jet printing synthesis onto different solid surfaces (such as ceramic, glass, quartz, paper, and cloth). Parallel syntheses of MMMOs libraries achieve greater stability, precision, highly dispersion, and uniformity. MMMOs libraries with varied composition, stoichiometries and self-assembled nanostructures can be prepared by ejecting precursors microdroplets via nozzles with the aid of a computer specification design file and software (>104 samples/day). This approach provide an efficient way to search through the largely unexplored universe of MMMOs with binary, ternary, and higher order for the discovery and optimization of better catalysts for photocatalytic hydrogen production by liquid-phase reforming of formaldehydewater solution.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
