Regulatory policies can have a significant impact on innovation in catalysis. Policies that promote environmental sustainability and energy efficiency can create a demand for new catalytic processes and materials. For instance, stricter emission regulations for industrial processes and vehicles spur the development of catalysts that can reduce harmful emissions. Government incentives, such as tax credits for research and development, can also encourage companies to invest in innovative catalytic technologies. Conversely, overly restrictive regulations may hinder innovation by creating barriers to experimentation and commercialization.
