“…Influences of Preparation Effects. A comparative study of the WO x dispersion on Mn-promoted tungstated zirconia isomerization catalysts prepared by conventional and CHT methods was presented by Hern andezÀPichardo et al 192 By isomerization of C5 and C6 light paraffin feedstocks to branched species aromatic hydrocarbons in gasoline pools can be substituted because of the high octane number of the branched species. Earlier studies on the isomerization of hydrocarbons 193 showed tungstated zirconia catalysts despite a low surface area to be active but their catalytic performance depending on the dispersion of the WO x phase on the support.…”

Rational materials design based on prior knowledge is attractive because it promises to avoid time-consuming synthesis and testing of numerous materials candidates. However with the increase of complexity of materials, the scientific ability for the rational materials design becomes progressively limited. As a result of this complexity, combinatorial and high-throughput (CHT) experimentation in materials science has been recognized as a new scientific approach to generate new knowledge. This review demonstrates the broad applicability of CHT experimentation technologies in discovery and optimization of new materials. We discuss general principles of CHT materials screening, followed by the detailed discussion of high-throughput materials characterization approaches, advances in data analysis/mining, and new materials developments facilitated by CHT experimentation. We critically analyze results of materials development in the areas most impacted by the CHT approaches, such as catalysis, electronic and functional materials, polymer-based industrial coatings, sensing materials, and biomaterials.

“…On the contrary, as also suggested by the XRD measurements, an increased amount of WO 3 covers preferentially the surface of LaO 2 CO 3 , thus affecting the optical properties of the compound, with the narrowing of the bandgap. For these reasons in the La‐5 %WO 3 spectrum the shoulder of the impurity levels is not detected [28] …”

Removal of Phthalates from Water by Unconventional La‐based/WO₃ Photocatalysts

La 2 O 2 CO 3 -WO 3 composites were here proposed as unconventional photocatalysts for the removal of phthalates in water. The high sorption properties of the lanthanum dioxide carbonate allowed a strong adsorption of the phthalates which facilitated the following solar photocatalytic degradation, further boosted by the addition of small amounts of WO 3 (1 wt %). On the contrary, a higher content of WO 3 had a detrimental effect due to the covering of the surface sites of La 2 O 2 CO 3 that inhibited the adsorption process. This double mechanism of strong adsorption-photocatalytic oxidation led, after 6 h of solar irradiation, to 67 % and 63 % dimethyl phthalate and di(2ethylhexyl)phthalate degradation, respectively. The phthalates were degraded to less persistent pollutants that, however, were completely removed after 9 h of irradiation. The La 2 O 2 CO 3 -WO 3 system appears promising for its application in the removal of the emerging contaminants from water.[a] E.

“…Recently, many companies have manufactured affordable robot systems in the field of laboratory equipment, significantly accelerating the reactant preparation process. Pichardo et al [46] employed HT experimentation techniques to synthesize a library containing 24 multicomponent Mn-WO x -ZrO 2 catalysts. A Cavro robot was introduced in their experiments for automated synthesis to dispense the precursor solutions, add reactants, and control the reaction conditions (e.g., temperature and speed of chemical dispensing).…”

The development of new catalysts is an urgent task in chemistry research because of the increasing demands for higher productivity and efficiency in modern industrial chemistry. High-throughput (HT) technologies have emerged as powerful accelerators for the discovery of new catalytic materials. Generally, HT techniques involve HT computational screening of catalytic materials and HT experimental approaches. Significant progress has been made in discovering and optimizing catalysts, which demonstrates the speed and economic advantages of HT methods in a matter of process within days and even hours, in contrast with traditional time-consuming trial and error experiments. From this perspective, the key processes of HT technologies for building a catalysts library are highlighted, including the virtual lab construction based on informatics tools and experimental data lab involving the following processes: 1) design of experiments; 2) reactants prepared manually or automatically; 3) constructing reactor that can well control the variations including materials diversity and reaction conditions (e.g., temperature and reaction time); 4) parallel characterization of fabricated catalysts. Moreover, the correlation between virtual lab and experimental data is discussed to inspire explorations in this field. Furthermore, several remaining challenges of HT technologies accompanied by possible research directions are presented to promote efforts in catalysts library creation.
