  2. Catalysis - Wikipedia

    en.wikipedia.org/wiki/Catalysis

    A true catalyst can work in tandem with a sacrificial catalyst. The true catalyst is consumed in the elementary reaction and turned into a deactivated form. The sacrificial catalyst regenerates the true catalyst for another cycle. The sacrificial catalyst is consumed in the reaction, and as such, it is not really a catalyst, but a reagent.

  3. Energy profile (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Energy_profile_(chemistry)

    Catalysts: There are two types of catalysts, positive and negative. Positive catalysts increase the reaction rate and negative catalysts (or inhibitors) slow down a reaction and possibly cause the reaction not occur at all. The purpose of a catalyst is to alter the activation energy.

  4. Activation energy - Wikipedia

    en.wikipedia.org/wiki/Activation_energy

    A catalyst is able to reduce the activation energy by forming a transition state in a more favorable manner. Catalysts, by nature, create a more "comfortable" fit for the substrate of a reaction to progress to a transition state. This is possible due to a release of energy that occurs when the substrate binds to the active site of a catalyst ...

    en.wikipedia.org/wiki/Stock_catalyst

    A stock catalyst can be either a sudden catalyst or an anticipated catalyst. Sudden catalysts cannot be anticipated and are announced suddenly by the company during a press release. [ 1 ] An example of a sudden catalyst is a company partnership since they are announced without prior notice to investors.

  9. Catalytic cycle - Wikipedia

    en.wikipedia.org/wiki/Catalytic_cycle

    In chemistry, a catalytic cycle is a multistep reaction mechanism that involves a catalyst. [1] The catalytic cycle is the main method for describing the role of catalysts in biochemistry, organometallic chemistry, bioinorganic chemistry, materials science, etc.
