Inkjet Printing Assisted Synthesis of Multicomponent Mesoporous Metal Oxides for Ultrafast Catalyst Exploration

We describe an inkjet printing assisted cooperative assembly method for high-throughput generation of catalyst libraries (multicomponent mesoporous metal oxides) at a rite of 1000,000-formulitions/hour with up to eight-component compositions The compositions and meso-structures of the libraries can be well-controlled and continuously varied. Fast identification of in inexpensive and efficient quaternary catalyst for photocatalytic hydrogen evolution is achieved via a multidimensional group testing strategy to reduce the number of performance validation experiments (25000-fold reduction over an exhaustive one-by-one search).
