Misrepresentation can occur due to various reasons: 1. Pressure to Publish: Researchers may feel the need to publish positive results quickly, leading to the temptation to embellish findings. 2. Funding Requirements: Exaggerating the potential of a catalytic material or process can make it easier to secure funding. 3. Commercial Interests: Companies might overstate the performance of a catalyst to gain a competitive edge in the market. 4. Human Error: Misinterpretation of data or unintentional errors in experimental design can lead to inaccurate results being reported.
