A two-day workshop activity is described in which postgraduate students are introduced to (i) the theory and application of Design-of-Experiments (DOE) approaches and (ii) the implementation of affordable automation technologies and related data analysis of a system of catalytic interest. This work involved the design and delivery of a short lecture to introduce the theory of DOE followed by practical demonstrations of the application of automation technologies. Specifically, a fractional factorial design was used to interrogate the input space-base, solvent, temperature, time-of the Suzuki-Miyaura cross-coupling (SMCC) of -bromoanisole and -fluorophenylboronic acid using automated solid and liquid handling robots and online HPLC analysis. This was supplemented by a second lecture following data acquisition in which the collected HPLC data was analyzed. The workshop was delivered to a cohort of 15 students at the postgraduate level. Pleasingly, students demonstrated a high degree of engagement with this course structure and reported an increased theoretical understanding of DOE approaches to reaction optimization.

Diethanolamine (DEA) can be used not only as a cement admixture but also to capture carbon dioxide (CO). However, the waste liquid treatment still faces the problems of high energy consumption and increasing environmental burden. The effects of DEA waste liquid (WL-DEA) with multiple cycles of CO absorption and desorption on the setting time, hydration temperature, mechanical strength, and microstructure of cement-based materials were explored.

The performance of the electrocatalytic CO reduction reaction (CORR) is highly dependent on the microenvironment around the cathode. Despite efforts to optimize the microenvironment by modifying nanostructured catalysts or microporous gas diffusion electrodes, their inherent disorder presents a significant challenge to understanding how interfacial structure arrangement within the electrode governs the microenvironment for CORR. This knowledge gap limits fundamental understanding of CORR while also hindering efforts to enhance CORR selectivity and activity.

Electrochemical methodologies offer a transformative approach to sustainable chemical synthesis by enabling precise, energy-efficient transformations. Here, we report the selective electrochemical N-formylation of methylamine using methanol as both reagent and solvent, facilitated by a simple glassy carbon electrode. Under optimized conditions, we achieve a faradaic efficiency (FE) of 34% for methylformamide synthesis in a neutral NaClO electrolyte.

Porous KTi(PO) nanoparticles are synthesized via a solvothermal method and subsequently modified with nitrogen-doped carbon layers by using polydopamine as the carbon source. The resultant KTi(PO)@N-doped carbon composite (KTP@NC) exhibits a preserved porous structure with abundant pores, facilitating ion diffusion and electrolyte infiltration. Various characterizations, including X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy, reveal the successful formation of an interconnected nitrogen-doped carbon network.

The design of highly efficient photocatalysts to photoreduce nitrogen (N) to ammonia (NH) under mild conditions is extremely challenging. In this work, various molar ratio of molybdenum (Mo) is incorporated into BiOCl via a hydrothermal process. The resulting Mo-doped BiOCl exhibits remarkable solar-driven activity for N photo fixation without any scavengers or sacrificial agents.
