The research presented in Ciarans' thesis aims to identify and investigate the synthesis and detailed characterisation of novel metal oxide precursors that could be utilised as anti-friction and anti-wear additives in automotive lubricants. Initially, this investigation was focused on designing precursors that offer comparable or superior tribological properties to commonly used additives such as MoDTC or ZDDP. These additives function by reducing friction and wear by facilitating the formation of lamellar sulfide materials and phosphate glasses respectively.

However, it is well-documented that the presence of byproducts containing both P and S have been known to impede the efficacy of catalytic converters. Therefore, the primary focus of this research is centred on alleviating the reliance on P and S-based precursor formulations. In response to these challenges, efforts are made to transition towards alternative precursors that mitigate the environmental impact on the catalytic converters and the surrounding ecosystem, with a particular focus on metal oxide-based precursors.

By addressing these concerns, this research contributes to the development of more environmentally friendly and novel precursors, potentially leading to enhanced engine performance and reduced environmental pollution.
