“…In the development of optimal catalysts in the steam reforming of alcohols, the support selection and the methods used in their synthesis are considered key factors for their catalytic performances. From a bibliographic search is observed how the scientific interest in layered double hydroxides (LDHs) materials as support of catalysts is recently increasing [26][27][28][29][30][31][32][33][34][35][36][37]. Moreover, positive feedback can be observed in the use of LDHs in SRE [38][39][40][41].…”

Four samples of Zn-hydrotalcite containing different amounts of Co (5, 10, 20, and 30 wt.%) have been synthesized and tested in the steam reforming of ethanol. The best results were obtained with the sample containing 20 wt.% of Co (20CoHT), with a complete conversion of ethanol and yields to hydrogen close to the equilibrium (73 mol.%). The physicochemical characterization of the samples by DRX, BET area and TPR indicates that the excellent performance exhibited by the sample containing 20 wt.% of Co is due to the higher percentage of reduced cobalt and lower crystallite size of metallic cobalt present in this sample (11 nm). Additional studies have been carried out to improve the stability of this catalytic material against deactivation by the incorporation of 1 wt.% of La. Stability studies were carried out using an industrial alcoholic waste as feed. Deactivation after 24 hours of reaction time was found lower for the catalyst containing La (20CoLaHT), confirming the positive effect of lanthanum on the catalytic stability. The results presented here show that it is possible to prepare a catalyst based on Co supported on Zn-hydrotalcite and promoted with La with improved ethanol conversion, high hydrogen selectivity, and high stability to produce hydrogen by the steam reforming of an industrial alcoholic waste without commercial value.

“…Therefore, the same strategies can be employed to enhance the sensors’ performance. Composite materials based on LDHs and carbon nanomaterials have been synthesized to fabricate sensors for enzyme-less detection of glucose [ 34 , 118 , 119 ], guanine [ 120 ], H 2 S [ 121 ], and dopamine [ 122 ] displaying superior performance thanks to the enhanced electrical conductivity. The sensor performances can be improved increasing the accessibility to the redox-active sites, if the conductive support is chemically modified with ultrathin LDH layers [ 123 , 124 , 125 ].…”

Synthesis and Characterization of Layered Double Hydroxides as Materials for Electrocatalytic Applications

Layered double hydroxides (LDHs) are anionic clays which have found applications in a wide range of fields, including electrochemistry. In such a case, to display good performances they should possess electrical conductivity which can be ensured by the presence of metals able to give reversible redox reactions in a proper potential window. The metal centers can act as redox mediators to catalyze reactions for which the required overpotential is too high, and this is a key aspect for the development of processes and devices where the control of charge transfer reactions plays an important role. In order to act as redox mediator, a material can be present in solution or supported on a conductive support. The most commonly used methods to synthesize LDHs, referring both to bulk synthesis and in situ growth methods, which allow for the direct modification of conductive supports, are here summarized. In addition, the most widely used techniques to characterize the LDHs structure and morphology are also reported, since their electrochemical performance is strictly related to these features. Finally, some electrocatalytic applications of LDHs, when synthesized as nanomaterials, are discussed considering those related to sensing, oxygen evolution reaction, and other energy issues.
