What are the disadvantages of olefin metathesis catalysts?5 answersOlefin metathesis catalysts face several challenges. Water presence can lead to catalyst decomposition, hindering metathesis reactions in water-rich environments and promoting unwanted reactions like DNA degradation. Some Mo-based catalysts exhibit reduced activity with longer chain α-olefins due to strong adsorption of metathesis products on the catalyst surface. Issues like low disproportionation activity and short catalyst lifespan have been addressed by developing catalysts containing elements like tungsten, molybdenum, and rhenium on specific carriers with controlled impurity levels. Sterically demanding indenylidene ligands in Ru-based catalysts can affect the first turnover event by influencing phosphine dissociation and metallacycle stability. These challenges highlight the importance of catalyst design and optimization for efficient olefin metathesis reactions.
What are the challenges of using oxygen evolution reaction?4 answersThe challenges of utilizing the oxygen evolution reaction (OER) include high overpotentials, catalyst instability, and the need for cost-effective and environmentally friendly catalyst materials.High overpotentials are required for the OER compared to other reactions, leading to sluggish kinetics and energy inefficiencies. Catalyst instability due to factors like mechanical peeling, active-site over-oxidation, and substrate corrosion poses a significant hurdle for long-term OER performance. Researchers are exploring various catalyst materials, such as silicate-stabilized Mn oxide and non-precious metal catalysts like NiFeOOH aerogels, to enhance OER efficiency and stability. Addressing these challenges is crucial for advancing technologies like polymer electrolyte membrane water electrolysis (PEMWE) for sustainable hydrogen production.
What are the disadvantages of high entropy oxides catalyst of OER?5 answersHigh entropy oxides (HEOs) used as catalysts for the oxygen evolution reaction (OER) present challenges despite their promising features. One drawback is the difficulty in epitaxial stabilization of thicker films due to the requirement of specific oxidation states, limiting the optimal thickness for enhanced OER activity. Additionally, the high chemical complexity of multimetallic HEO catalysts can hinder the preparation of elemental homogenous catalysts and understanding their synergistic effects during the OER process, complicating their design. While HEOs offer abundant active sites and unique electronic properties, these complexities can pose obstacles in practical applications, requiring further research to overcome these limitations for efficient OER catalysis.
What are the limitations of the new catalyst?5 answersThe limitations of the new catalyst include the limited ability to control its catalytic properties and the limited stability of the active species under reaction conditions. Additionally, the catalyst cannot enable the distillation of entanglement from a bound entangled state, even if it becomes correlated with the system of interest. Furthermore, the catalyst cannot enable reversibility in the manipulation of quantum coherence, establishing stronger restrictions on asymptotic catalytic transformations. In the field of quantum thermodynamics, there are significant restrictions on arbitrary state transformations under dimension or mean energy bounds, which also apply to thermal catalysis.
What are disadvantages of using OERs?5 answersThe disadvantages of using OERs include the reduction of social relations and interaction, the formation of individualism, and the difficulty of transitioning from a symbolic form to practical actions.

What are disadvantages of using OERs in teaching?5 answersUsing OERs in teaching has some disadvantages. One of the negative aspects is the reduction of social relations and interaction, leading to the formation of individualism. Another disadvantage is the difficulty of transitioning from a symbolic form to practical actions, which can hinder the learning process. Additionally, some university teachers may not feel confident in their skills for OER development and may not see the need to share all the resources they create. These challenges can limit the effective use and creation of OERs in teaching.
