Solid-state catalysts for selective oxidations have been prepared by simple traditional protocols including impregnation, precipitation, solid-state reaction, and so on. Although these catalyst preparation protocols are convenient to form new or improved catalysts, a huge number of practical experiments have been inevitably necessary. This situation will be even more difficult because solid-state catalysts become increasingly complex in order to introduce multifunction. It is time that catalyst researchers should devote their efforts to establish new synthetic methodology to improve the situation and ultimately create new catalysts. Here, we propose a new catalyst synthesis approach, that is, unit synthesis, to produce high dimensionally structured crystalline complex metal oxide catalysts. By applying this synthesis methodology, we have been able to synthesize several new crystalline complex metal oxides active for catalytic selective oxidations. In this Perspective, crystalline Mo3VOx oxides and crystal...
