“…Moreover, the average crystallite diameter of Ni calculated from H 2 uptake over Ni-ZrO 2 -CR catalysts was larger than that determined by XRD. This can be possibly attributed to that some Ni particles entered into amorphous ZrO 2 matrix and surrounded by ZrO 2 particles [30,31]. Therefore, it was difficult to reduce the NiO particles completely under the prereduction conditions during H 2 chemisorption, which is in consistent with the results of H 2 -TPR.…”

“…Equivalent results were also reported in case of the ablation of Zn in water producing Zn@ZnO core‐shell NPs . These ignoble metal NPs exhibiting an oxide shell represent interesting structures for the preparation of numerous heterogeneous catalysts like e. g. electro‐, methanization‐, partial oxidation‐ or water gas shift reaction‐ catalysts.…”

Due to material gaps and synthesis‐related cross‐correlations in heterogeneous catalysis, chemists and physicists are constantly motivated to develop novel catalyst preparation methods for independent control of morphology, size, and composition. Within this article, advances, opportunities, and the current limits of laser‐based catalyst preparation technique, as well as synergies with conventional methods will be reviewed in terms of purity, particle size, morphology, composition, and nanoparticle‐support interaction. It will be shown, that the surfactant‐free particles represent ideal model materials to validate kinetic models and conduct parametric activity studies by independent adjustment of functional properties like nanoparticle size, composition, and load. Consequently, the importance of transient plasma dynamics tailoring nanoparticle formation will be pointed out, comparing experimental studies with own calculations and novel simulations taken from literature. Finally, perspectives of surfactant‐free colloidal nanoparticles for unrevealing active sites in heterogeneous catalysts are presented.

“…High specific surface area induces the formation of many electrical double layers and employs more electroactive species in pseudocapacitive reactions [5]. Mesoporous NiO nanoparticle can be produced, by using a soft or hard template and precipitation methods [7,8]. The hard template, including mesoporous silica or cabon materials, requires an additional step for the preparation of the mesoporous scaffold, which is time and energy consuming.…”

Abstract. Environmentally recycled liginsulfonate were successfully employed for the facile synthesis of mesoporous NiO materials. The XRD, SEM, TEM and N 2 adsorption-desorption analysis were performed for characterizing the structure and surface properties of resultant NiO. The proximate globular structure of lignin macromolecules played an templating role in the formation of mesoporous framework of NiO. The fabricated NiO nanostructures had high specific surface area (193.8 m 2 /g), large pore volume (0.42 cm 3 /g), and narrow pore size distribution making them ideal candidates for supercapacitor applications. CV, ESI and galvanostatic constant-current charge/discharge tests showed that the fabricated mesoporous NiO had high specific capacitance (342 F·g −1 ) and good circulatory stability. Furthermore, the mesoporous NiO showed a good rate capability, which is due to that the ordered mesopores did not limit the ion motion within the pores. The results suggest that resultant NiO mesostructures are a promising supercapacitor electrode material.
