Non-noble metals such as Cu and Ni photodeposited on commercial TiO2 play an important role as mono or bimetallic co-catalysts that strongly improve the photo-reforming of cellulose producing both H2 and valuable organic acids in solution. In this study, preparation variables like the total metal loading (nominal 1 and 5 wt%, with a weight ratio Cu:Ni = 1:1) and different Cu-Ni photodeposition sequence (consecutive (first Cu and then Ni and vice versa), or simultaneous) were studied, resulting in a set of twelve photocatalysts. All the metal-loaded photocatalysts exhibit enhanced H2 production with respect to bare TiO2 with total H2 generation and product selectivity influenced by the metal content, the interaction between both metals, and the state of the deposited species. The last two properties have shown to be highly dependent on the photodeposition sequence. The higher metal loadings lead to the less active photocatalysts, mainly attributed to an excessive coverage of the TiO2 surface. Notably, the stepwise incorporation of Cu and Ni leads to more active photocatalysts than the simultaneous photodeposition. The photocatalyst with 1 wt% metal loading prepared via sequential NiCu deposition provides the highest hydrogen generation, 489 μmol/h · gcat. This value is among the highest reported up to now for noble-metal-free photocatalysts.

To train LLM using in-context learning techniques, it is necessary to provide it with knowledge in a way that is understandable to the model. To do this, it is provided with a prompt indicating the level of specialization along with certain guidelines and requirements that the LLM must take into account when reasoning, and a dataset with the knowledge that the LLM must learn, which in this case is formalized through a series of questions and answers about the work environment. The results generated by the LLM after training with the prompt and the dataset are also collected.
